Section I | 11 | Overview | 10 | ||
02 Mandler | 23 | Some uses of consciousness (1975) | 12 | ||
Crick & Koch; Consciousness and Neuroscience | 35 | Consciousness and Neuroscience (1998) | 12 | ||
Crick & Koch; Consciousness and Neuroscience | 35 | It is probable that, at any moment, some active neuronal processes in your head correlate with consciousness, while others do not -- what is the difference between them? | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 36 | Why are we conscious? | 1 | ||
Crick & Koch; Consciousness and Neuroscience | 36 | Philosophers, in their carefree way, have invented a creature they call a "zombie," who is supposed to act just as normal people do but to be completely unconscious. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 37 | It is often stated that a trained tennis player reacting to a fast serve has no time to see the ball -- the seeing comes afterwards. | 1 | ||
Crick & Koch; Consciousness and Neuroscience | 37 | To be aware of an object or event, the brain has to construct a multilevel, explicit, symbolic interpretation of part of the visual scene. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 37 | By multilevel symbolic interpretation we mean, loosely, the different levels and in the visual hierarchy. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 37 | By explicit representation, we mean a "smallish" group of neurons to represent some aspect of visual scene. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 37 | How many neurons are likely to be in a "smallish" group? This is not yet known, but we would guess that the number to represent one aspect is likely to be closer to 102 -- 103 than to 104 -- 106. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 37 | While the information needed to represent a face is contained in the firing of ganglion cells in the retina, there is no explicit representation of the face there. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 37 | A representation of an object or an event will usually consists of representations of many of the relevant aspects of it, and these are likely to be distributed over different parts of the visual system. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 37 | How these different representations are bound together is known as the binding problem. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 37 | Much neural activity is usually needed for the brain to construct a representation. Most of this is probably unconscious. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 38 | Conscious visual representation is likely to be distributed over more than one area of the cerebral cortex and possibly over certain subcortical structures as well. | 1 | ||
Crick & Koch; Consciousness and Neuroscience | 38 | We have argued that conscious visual representation is not located in cortical area V1 (also called the striate cortex or area 17). | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 38 | The activity in V1 may be crucial for most forms of vivid visual awareness. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 38 | What is essential for visual consciousness? | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 38 | The term 'visual consciousness' almost certainly covers a variety of processes. When you are looking at a visual scene, the experience is very vivid. This should be contrasted with the much less vivid and less detailed visual images produced by trying to remember the same scene. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 38 | a vivid recollection is usually called a hallucination. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 38 | It is possible that dimmer visual recollections are mainly due to the back pathways in the visual hierarchy acting on the random activity in the earlier stages of the system. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 38 | Some form of very short-term memory seems almost essential for consciousness. This memory may be very transient, lasting for only a fraction of a second. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 38 | Edelman has used the phrase 'the remembered present.' | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 38 | The existence of iconic memory is well-established experimentally. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 38 | Ever present eye movements. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 38 | Although working memory expands the timeframe of consciousness, it is not obvious that it is essential for consciousness. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 38 | The episodic memory enabled by the hippocampal system is not essential for consciousness, though a person without it is severely handicapped. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 39 | Consciousness is enriched by visual attention, though attention is not essential for visual consciousness. | 1 | ||
Crick & Koch; Consciousness and Neuroscience | 39 | Attention is broadly of two types -- (1) bottom-up, caused by the sensory input, and (2) top-down, produced by the planning parts of the brain. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 39 | Visual attention can be directed to either a location in the visual field or to one or more (moving) objects. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 39 | To interpret the visual input, the brain must arrive at a coalition of neurons whose firing represents the best interpretation of the visual scene, often in competition with other possible but less likely interpretations. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 39 | Classical blindsight | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 40 | Some researchers considered the ventral stream of visual processing to be largely conscious. | 1 | ||
Crick & Koch; Consciousness and Neuroscience | 40 | Researches have hypothesized that the direct projections from parietal cortex into the premotor areas are unconscious, whereas projections to the premotor areas via the prefrontal cortex are related to consciousness. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 40 | Fuster's diagram showing fiber connections between cortical regions participating and a perception-action cycle. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 40 | The little that is known of the neural anatomy would suggest that there are likely to be multiple cortical streams, with numerous anatomical connections between them. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 40 | There are numerous pathways for most intermediate levels of the visual system to intermediate frontal regions. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 40 | Brain always tries to use the quickest appropriate pathway for the situation at hand. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 41 | Bistable percepts | 1 | ||
Crick & Koch; Consciousness and Neuroscience | 41 | It is not obvious where to look in the brain for the two alternative views of the Necker cube. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 41 | Responses in the visual system during binocular rivalry. Visual input into each eye is different, but perceptually overlapping. Input is constant, at the percept changes. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 43 | Electrical brain stimulation studies, with the roots going back to Penfield (1958), involves directly stimulating cortex or related structures in order to evoke a percept or behavioral act. | 2 | ||
Crick & Koch; Consciousness and Neuroscience | 43 | Crick and Koch have argued that a person is not directly conscious of the features represented by the neural activity in primary visual cortex. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 43 | Activity in V1 may be necessary for vivid and veridical visual consciousness (as it is activity in the retinae), but the firing of none of the neurons in V1 directly correlates with what we consciously see. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 44 | V1 cells do not project directly to any part of frontal cortex. | 1 | ||
Crick & Koch; Consciousness and Neuroscience | 44 | Nor do the V1 cells project to the caudate nucleus of the basal ganglia, the intralamina nuclei of the thalamus, the claustrum, nor to the brainstem, with the exception of a small projection from peripheral V1 to the pons. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 44 | If the structure of perception does not map to the receptive field properties of V1 cells, it is unlikely that these neurons directly give rise to consciousness. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 45 | Severe damage to V1 is compatible with visual imagery in patients. | 1 | ||
Crick & Koch; Consciousness and Neuroscience | 46 | We hypothesize that the NCC must have access to explicitly encoded visual information and directly project onto the planning stages of the brain, associated with the frontal lobes in general and with the prefrontal cortex in particular. | 1 | ||
Crick & Koch; Consciousness and Neuroscience | 46 | We predict that patients unfortunate enough to have lost their entire prefrontal cortex on both sides (including Broca's area) would not be visually conscious, although they might still have well preserved, unconscious, visual-motor abilities. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 46 | Gamma oscillations | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 46 | The existence of gamma oscillations remains in doubt in higher visual cortical areas. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 46 | We remain agnostic with respect to the relevance of gamma oscillations to conscious perception. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 46 | It is possible that gamma oscillations subserve attention or figure-ground in early visual processing. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 46 | At this time there is no agreed philosophical answer to the problem of consciousness, except that most living philosophers do not believe in an immaterial soul that is distinct from the body. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 46 | While philosophers have in the past raised interesting questions and pointed to possible conceptual confusions, they have had a very poor record, historically, in arriving at valid scientific answers. For this reason, neuroscientists should listen to the questions philosophers raise but should not be intimidated by their discussions. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 47 | Problem of qualia | 1 | ||
Crick & Koch; Consciousness and Neuroscience | 47 | The problem of qualia is what Chalmers (1995) calls "The Hard Problem" -- a full account of the manner in which subjective experience arises from cerebral processes. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 47 | What is the function of conscious experience? | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 47 | Visual consciousness is largely private, i.e. it is inherently impossible to communicate the exact nature of what we are conscious of. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 47 | To be conscious, there must be an explicit representation of each aspect of visual consciousness at each successive stage in the visual cortex. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 47 | It is not possible to convey with the words the exact nature of a subjective experience. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 47 | It is possible to convey a difference between subjective experiences -- to distinguish between red and orange, for example. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 48 | If the neural correlate of blue depends on my past experience, and if my past experiences significantly different from yours, then it may not be possible to deduce that we both see blue in exactly the same way. | 1 | ||
Crick & Koch; Consciousness and Neuroscience | 48 | We suspect that meaning arises from the correlated firing of patterns of neurons and from the linkages to related representations. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 48 | Neurons may be connected in a vast associational network, similar to a relational database. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 48 | How are useful neuronal associations derived? The obvious idea is that they depend very largely on the consistency of the interactions with the environment, especially during early development. Meaning can then be acquired later in life. | 0 | ||
Crick & Koch; Consciousness and Neuroscience | 50 | The explanation of consciousness is one of the major unsolved problems of modern science. | 2 | ||

Francis Crick; Searchlight Hypothesis | 263 | Function of the thalami reticular complex -- the searchlight hypothesis. (1984) | 28 | ||
Francis Crick; Searchlight Hypothesis | 264 | The thalamus is often classified in two parts -- the dorsal thalamus, which is the main bulk of it, and the ventral thalamus. | 1 | ||
Francis Crick; Searchlight Hypothesis | 264 | Almost all input to the cortex, with the exception of the olfactory input, passes through the thalamus. | 0 | ||
Francis Crick; Searchlight Hypothesis | 264 | The thalamus
is sometimes called the gateway to the cortex. . |
0 | ||
Francis Crick; Searchlight Hypothesis | 264 | For each projection from a region of the thalamus there is a corresponding reverse projection from that part of the cortex to the corresponding region of the thalamus. | 0 | ||
Francis Crick; Searchlight Hypothesis | 264 | The reticular complex is a thin sheet of neurons, in most places only a few cells thick, which partly surrounds the dorsal thalamus. | 0 | ||
Francis Crick; Searchlight Hypothesis | 264 | All axons from the thalamus to the cerebral cortex pass through the reticular complex, as do all of the reverse projections from the cortex to the thalamus. | 0 | ||
Francis Crick; Searchlight Hypothesis | 264 | The intralamina nuclei of the thalamus, which project very strongly to the striatum, also send their axons through the reticular complex, as may some of the axons from the globus pallidus that project back to the thalamus. | 0 | ||
Francis Crick; Searchlight Hypothesis | 265 | Many of the axons that pass in both directions through the reticular complex give off collaterals that make excitatory synaptic contacts. | 1 | ||
Francis Crick; Searchlight Hypothesis | 267 | von der Malsburg synapses | 2 | ||
Francis Crick; Searchlight Hypothesis | 267 | The only plausible way to create a neural pathway in a short time is to strengthen an existing synapse in some way. | 0 | ||
Francis Crick; Searchlight Hypothesis | 267 | In 1981 von der Malsburg put forward in a little-known paper the idea of temporarily-strengthened existing synapses to form a pathway. | 0 | ||
Francis Crick; Searchlight Hypothesis | 267 | von der Malsburg proposed that when there is a strong correlation between presynaptic and postsynaptic activity, the strength of the synapse is temporarily increased -- a dynamic version of Hebb's well-known rule. | 0 | ||
Francis Crick; Searchlight Hypothesis | 267 | von der Malsburg further proposed that with uncorrelated pre- and postsynaptic signals, the synaptic strength would be temporarily decreased below its normal resting value. | 0 | ||
Michael Posner; Attention | 279 | Attention -- the mechanisms of consciousness. (1994) | 12 | ||
Michael Posner; Attention | 279 | An understanding of consciousness must rest on an appreciation of the brain networks that subserve attention. | 0 | ||
Michael Posner; Attention | 284 | The anatomy of the anterior cingulate provides pathways for connecting it to both the posterior parietal area and to anterior areas active during language tasks. | 5 | ||
Michael Posner; Attention | 284 | Lateral areas of the prefrontal cortex play a key role in holding online a representation of past events. | 0 | ||
Michael Posner; Attention | 284 | While specialized areas of the lateral prefrontal cortex appeared to hold the relevant information online, the anterior cingulate would be playing a role in the executive functions of awareness and control. | 0 | ||
Michael Posner; Attention | 285 | Edelman views the cingulate and hippocampus as involved in the integration of interoceptive and exteroceptive information needed for conscious processing. | 1 | ||
Michael Posner; Attention | 286 | Reentrant processing -- higher-level associations are made by fibers that reenter the brain areas which processed the initial input. | 1 | ||
Michael Posner; Attention | 286 | Results of attentional control are widely distributed, resulting in amplification of activity in the anatomical areas that originally computed that information. | 0 | ||
Michael Posner; Attention | 287 | Anterior cingulate connections to limbic, thalamic, and basal ganglia pathways distribute prefrontal midline network activity to widely dispersed connections involved in cognitive computations. | 1 | ||
Michael Posner; Attention | 287 | Neurotransmitter norepinephrine appears to be involved in maintaining the alert state. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 291 | Attention, Awareness, and the Triangular Circuit. (1997) | 4 | ||
LaBerge; Attention, the Triangular Circuit | 292 | Visual shapes are coded in clusters of neurons within the inferotemporal cortex (IT). | 1 | ||
LaBerge; Attention, the Triangular Circuit | 292 | Visual locations are coded in clusters of neurons within the posterior parietal cortex (PPC). | 0 | ||
LaBerge; Attention, the Triangular Circuit | 292 | Plans of actions and semantic attributes of objects involve codes that appear to be distributed across specific modules of the frontal cortex. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 292 | The controlling agent of attention is presumed to be encoded within specific areas of the prefrontal cortex (PFC). | 0 | ||
LaBerge; Attention, the Triangular Circuit | 292 | The controlling modules of the prefrontal cortex (PFC) are influenced by the basal ganglia, which are closely connected with the motivation-related hypothalamus. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 292 | Attentional operations exert their effects all ongoing cognitive related events by modulating the activity levels of neurons in the cerebral cortex. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 292 | The functional unit of the cerebral cortex is widely assumed to be not the individual neuron but ensembles of neurons. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 292 | Physiologists have assumed that the functional unit is the group of neural circuits contained in the vertical, cylinder-like structures of the cortical sheet call cortical columns. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 292 | A cortical column corresponds to the mass of neural tissue lining under a 1 mm x1 mm square area along the surface of the cortex and spanning the 1.5- to 2.0-mm thickness of the cortical sheet. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 293 | The number of neurons contained within the typical cortical column is said to be on the order of 100,000, while a typical column in the area V1 contains nearer to 180,000 neurons. | 1 | ||
LaBerge; Attention, the Triangular Circuit | 293 | The cortical column is sometimes subdivided into minicolumns of various sizes, having widths of about 400, 200, and 30 µ wide, containing about 23,000, 5500, and 140 neurons, respectively. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 293 | Vertical groups of neurons are centered around the long vertical dendrites of layer 5 neurons, forming a cylinder-like volume having a diameter of approximately 30 µ. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 293 | The minicolumn, which contains about 140 neurons, has been proposed as a functional unit of the cortex. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 293 | Axons of layer 5 neurons provide the major source of inputs to the thalamic relay neurons in the triangular circuit. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 293 | Since it is highly likely that minicolumns function in groups, it seems appropriate to use the term columns to refer to the layer 5 neuron groups. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 293 | Anatomical evidence indicates that the functional unit of the cerebral cortex is a columnar cluster of neuronal circuits, with a width that varies between 0.5 and 1.0 mm, so that a column contains on the order of 50,000 to 100,000 neurons. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 293 | The appropriate level of description of function taking place within a column appears to be not the individual neurons, nor a local circuit of several neurons, but rather in large bundle of circuits, whose organization is tailored to the particular function of that column. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 293 | It is not implied that a given cognitive event corresponds to one cortical column. It seems more likely that combinations of cortical columns within and between cortical regions constitute the cognitive unit. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 294 | It is proposed that simultaneous activity in columns of two or more separated cortical regions define the attentional event, so that, regarded as a unit of cognition, the attentional event involves not one but two or more functional units of the cerebral cortex. | 1 | ||
LaBerge; Attention, the Triangular Circuit | 294 | Viewed cortically, the expression of attention corresponds to a difference in activity levels between the column clusters corresponding to the attended (target) components and its neighboring (distractor) components. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 295 | The expression of attention could be based on one of three types of operations -- enhancement of the target columns, suppression of surrounding distractor columns, or a combination of these two operations. | 1 | ||
LaBerge; Attention, the Triangular Circuit | 297 | Selection of the target column requires top-down signals, particularly when the target-distractor similarity is high and there is no appreciable preattentive "popout." | 2 | ||
LaBerge; Attention, the Triangular Circuit | 299 | Triangular circuit | 2 | ||
LaBerge; Attention, the Triangular Circuit | 299 | Most of the knowledge we have of cortical and thalamic circuitry has been obtained from studies of the primary visual cortex and its adjacent areas. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 299 | The hypothesized triangular circuit involves connections between two cortical columns together with connections to the thalamus. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 299 | In a triangular circuit involving areas V1 and V2, the direct, (forward) fibers arise from layer 2 of the V1 column and terminate in the middle layers of the V2 column. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 299 | The indirect connecting fibers of the triangular circuit connect V1 and V2 columns via a thalamic relay in the pulvinar nucleus of the thalamus. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 300 | The triangular circuit begins with neurons in a V1 column that connect with a V2 column by a direct connection and by an indirect connection by way of the thalamus. | 1 | ||
LaBerge; Attention, the Triangular Circuit | 300 | Layer 5 neurons fire in bursts of a few spikes at rates at least as high as 250 Hz, with intrinsic intrabursts firing rates on the order of 15 Hz. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 300 | The intrinsically spiking layer 5 neurons synapse near the cell bodies of thalamic neurons and are therefore in a privileged position to drive the spike outputs of the cell body. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 300 | It is conjectured that the thalamocortical loop, involving the ascending thalamic relay fibers together with the feedback fibers from layer 6 neurons, has the ability to enhance firing rates of input fibers arriving from layer 5 cells of another column. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 301 | The triangular circuit that flows through thalamic neurons contains characteristics that can greatly enhance the firing rates of the layer 5 output neurons from the column of origin, while this output is being transmitted to the middle layers of the destination column. | 1 | ||
LaBerge; Attention, the Triangular Circuit | 301 | Since all regions of the cortex are connected with the thalamus, it seems highly probable that the triangular circuit exists wherever cortical columns in one area communicate with columns in another area. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 301 | The set of triangular circuits of interest in the present discussion are those that project activation in the top-down direction to posterior cortical columns in which attention is expressed. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 302 | The DLPFC area is crucially involved in voluntary control of attention for locations, while the VLPFC area is crucially involved in voluntary control of attention for shape and color. | 1 | ||
LaBerge; Attention, the Triangular Circuit | 302 | Several PET experiments with humans have shown activation of the pulvinar during the visual attention. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 303 | Occipital temporal areas and posterior parietal areas, which are closely connected with the pulvinar nucleus, are presumed to exhibit expressions of attention to shapes and locations. | 1 | ||
LaBerge; Attention, the Triangular Circuit | 303 | PET studies show activation both in thalamic nuclei and in cortical areas of attentional expression and attentional control that are reciprocally connected with the thalamic nuclei. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 304 | The thalamus serves as the mechanism that amplifies signals sent (top-down) from regions of attentional control to regions of attentional expression located in posterior and anterior cortical areas. | 1 | ||
LaBerge; Attention, the Triangular Circuit | 305 | A well-chosen metaphor can sometimes promote the understanding of complex systems of operations. | 1 | ||
LaBerge; Attention, the Triangular Circuit | 309 | Attention is assumed to be an event in the brain having three aspects that are connected by the triangular circuit. | 4 | ||
LaBerge; Attention, the Triangular Circuit | 309 | Three aspects of attention are: -- (1) expression of attention in cortical columns, (2) the mechanism that directly activates the columns, and (3) the control over which columns will express attention and how intense the expression will be. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 309 | For the expression of attention, columns in the posterior and anterior cortex that serve cognitive functions, such as perceptions of objects and attributes, and the organization and execution of action plans. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 309 | For the mechanism of attention, column-like sectors of thalamic nuclei, whose excitatory neurons activate neurons in the corresponding cortical columns. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 309 | For the control of attention, cortical columns of the prefrontal regions of the anterior cortex. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 309 | The triad of sites connected by the triangular circuit is initially activated by two different classes of sources, one within the system and one outside the system. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 310 | Internal sources normally activate the triangular circuit at the prefrontal control node. | 1 | ||
LaBerge; Attention, the Triangular Circuit | 310 | External sources are sensory stimuli that activate the cortical column site where attention is eventually expressed. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 310 | For highly routine situations, much of the object identification and action selection occur automatically, without the need for prefrontal control operating through the triangular circuit. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 310 | There are situations that invites us to savor the activity in particular cortical columns that serve sensations and feelings. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 310 | Attentional system enhances and sustains the sensations. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 310 | The necessary conditions for an awareness event is the existence of an attentional event, where the attentional event is defined by the activity of a triangular circuit of attention, which includes controlling columns located in the prefrontal cortex. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 311 | Activity in both thalamic and cortical structures (as well is and brainstem reticular nuclei) is a necessary and sufficient condition for the state of waking consciousness. | 1 | ||
LaBerge; Attention, the Triangular Circuit | 311 | Researchers have implicated the intralaminar nuclei of the thalamus in awareness, owing in part to their widespread connections across the cortex, their direct efferents to the basal ganglia, and their sensitivity to very small lesions. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 311 | The broad cortical distribution of brainstem neuromodulatory fibers, together with that of the intralamina thalamic fibers, serve to modulate general states of waking and alertness, which are preconditions for the more local activation patterns required for attention and awareness. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 311 | Distinction between the brain state of wakefulness and the state of attending to one of the many available cognitive aspects of wakefulness | 0 | ||
LaBerge; Attention, the Triangular Circuit | 311 | Awareness introduces an agent involved when attention is voluntarily directed to some event. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 311 | Role of references to the self in states of awareness. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 311 | The event of awareness requires that attention be directed to the regions where the self is expressed at the same time that attention is directed to the cortical regions where the object is expressed. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 311 | To distinguish the two kinds of triangular attention circuits, they will be labeled object-attended and self-attended circuits. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 312 | As a result of the temporal coincidence between the two triangular circuits, not only is attention being directed to the self along with attention to an object, but attention is being directed to the self doing the control of attention to an object. | 1 | ||
LaBerge; Attention, the Triangular Circuit | 312 | Attention to self-representation is assumed to involve the triangular circuit in a manner similar to attention to objects of perception, cognition, and action. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 312 | Bodily landscapes and verbal categories are represented by sets of corresponding cortical columns whose activity is controlled by voluntary prefrontal columns acting through the thalamus in triangular circuits. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 312 | Neural activity does not produce an awareness event unless the prefrontal area amplifies that activity to a particular level and sustains it there for some minimum duration. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 312 | In the pathological condition of depersonalization, the self-representation is dissociated from the perception of the body, so that perceptions and actions by the body are believed to be happening to someone other than the self. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 313 | The pathological condition of depersonalization, in which self-representation is dissociated from the perceptions of the body could occur in the prefrontal areas where the controls of attention to the self-representations and to the object representations (and action representations) are closely related. | 1 | ||
LaBerge; Attention, the Triangular Circuit | 313 | Prefrontal area is believed to have a crucial role in the temporal integration of operations that control the actions. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 313 | If defects occur in the temporal coordination of the actions controlling activities in the self-attended and object-attended triangular circuits, then the person's experience of self as an agency of control could be compromised, resulting in the observed disorder of depersonalization, which disrupts the sense of awareness. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 313 | Relatively brief durations of combined object-attended and subject-attended events suffice for a realization event of awareness. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 313 | Sensations of the bodily-landscape kind are typically described as "feelings." | 0 | ||
LaBerge; Attention, the Triangular Circuit | 313 | Sensations and feelings vary in intensity, and it is assumed that the activities in the prefrontal cortex, acting through the in attentional triangular circuit, are able not only to prolong sensations and feelings but to modulate their levels of intensity. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 313 | Individuals sometimes "forget themselves" when they are writing, or engaged in vigorous conversation, or enraptured by music. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 314 | Attention to an object requires the simultaneous activity of three brain regions that are connected by a triangular circuit, and awareness of an object requires an additional component, which is attention to some representation of the self. | 1 | ||
LaBerge; Attention, the Triangular Circuit | 314 | For both kinds of attention, object-attention and self-attention, the three types of brain regions connected by the triangular circuit are cortical columns of attentional expression, a group of thalamic neurons that enhance activities in these columns, and a set of prefrontal cortical columns that control the choice of columns and control the level and duration of enhanced activity. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 314 | The thalamic component of the attentional triangular circuit operates by modulating firing rates in a column without changing the informational signal existing in that column. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 314 | The expression of attention in a set of cortical columns may involve widely separated columns, such as attending both to a particular body shape and to its direction of movement. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 314 | The expression of attention to self-representations may involve widely separated cortical columns corresponding to the bodily landscape and/or cortical columns corresponding to verbal-based memories of autobiographical events. | 0 | ||
LaBerge; Attention, the Triangular Circuit | 314 | An attention event is a necessary but not sufficient condition for and awareness event, so that there can be attention without awareness, but no awareness without attention. | 0 | ||

Baars; Essential Sources | 321 | Immediate memory is closely associated with consciousness. (2003) | 2 | ||
Baars; Essential Sources | 321 | In immediate memory, faded items can be retrieved intact for about 10 seconds. | 0 | ||
Baars; Essential Sources | 322 | The part of immediate memory that can be rehearsed is now usually call working memory. | 1 | ||
Baars; Essential Sources | 322 | With rehearsal, we can recall about 7 items, and without rehearsal between 3 and 4 items. | 0 | ||
Baars; Essential Sources | 322 | Chunking -- information that can be coherently organized can be treated as a single element in working memory. | 0 | ||
Baars; Essential Sources | 322 | Working memory depends fundamentally on long-term memory. | 0 | ||
Baars; Essential Sources | 322 | Working memory may be nothing but the currently activated, separate components of a long-term memory. | 0 | ||
Baars; Essential Sources | 322 | Working memory is not the same as consciousness, but conscious experience and working memory are closely related. | 0 | ||
Baars; Essential Sources | 323 | It is useful to treat consciousness as a kind of momentary working memory. | 1 | ||

Atkinson & Shiffrin; Short-Term Memory | 373 | All phases of memory are seen to consists of small units of information that are associatively related. | 0 | ||
Atkinson & Shiffrin; Short-Term Memory | 374 | Our account of short-term and long-term storage does not require that the stores necessarily be in different parts of the brain or involve different physiological structures. | 1 | ||
Atkinson & Shiffrin; Short-Term Memory | 374 | Short-term memory may be considered as simply a temporary activation of some portion of long-term memory. | 0 | ||
Atkinson & Shiffrin; Short-Term Memory | 374 | We tend to equate the short-term memory with consciousness, i.e. the thoughts and information of which we are currently aware can be considered part of the contents of the short-term memory. | 0 | ||
Atkinson & Shiffrin; Short-Term Memory | 375 | Because consciousness is equated with short-term memory and because control processes are centered in and act through it, the short-term memory is considered a working memory -- a system in which decisions are made, problems are solved, and information flow is directed. | 1 | ||
Atkinson & Shiffrin; Short-Term Memory | 375 | Retrieval of information from short-term memory is quite fast and accurate. | 0 | ||
Atkinson & Shiffrin; Short-Term Memory | 375 | Retrieval time for information in short-term memory such as letters and numbers ranges from 10 to 30 ms per character. | 0 | ||
Atkinson & Shiffrin; Short-Term Memory | 375 | Retrieval of information from long-term memory is considerably more complicated. So much information is contained in the long term memory that the major problem is finding access to some small subset of the information. | 0 | ||

Goldman-Rakie; Prefrontal Landscape | 396 | Dorsolateral prefrontal cortex has a generic function -- "on-line" processing of information or working memory in the service of a whole range of cognitive functions; (2) the process is iteratively represented throughout several and possibly many subdivisions of the prefrontal area; (3) each autonomous subdivision integrates attentional, memorial, motor and possibly affective dimensions of behavior by virtue of network connectivity with relevant sensory, motor, and limbic areas of the brain | 1 | ||

Shevrin; Psychological Unconscious | 541 | Behaviorism, reacting against the methodological deficiencies of introspection, not only rejected the unconscious but also rid itself of consciousness. | 0 | ||
Shevrin; Psychological Unconscious | 541 | For William James (1890), consciousness was the very subject matter of psychology. | 0 | ||
Shevrin; Psychological Unconscious | 541 | Psychoanalysis, as reflected in much of clinical practice, has continued to base itself on unconscious mental processes. | 0 | ||
Shevrin; Psychological Unconscious | 543 | Selective Attention | 2 | ||
Shevrin; Psychological Unconscious | 543 | Inherent in all the major models of attention is the assumption that at least part of the cognition related to attention takes place outside of awareness. | 0 | ||
Shevrin; Psychological Unconscious | 545 | In the course of perceptual processing the stimulus makes contact with long-term memory prior to the point at which awareness occurs. | 2 | ||
Shevrin; Psychological Unconscious | 545 | Suggests that processing outside of awareness is qualitatively different from processing within awareness. | 0 | ||
Shevrin; Psychological Unconscious | 545 | Consciousness is bound up with processes that involve a limited capacity system. This imposes a serial order upon what are essentially widespread parallel processes initiated by a stimulus. | 0 | ||
Shevrin; Psychological Unconscious | 546 | In selective attention, an initial phase of cognitive activity occurs outside of awareness. | 1 | ||
Shevrin; Psychological Unconscious | 546 | Processes outside of awareness interact with and influence ongoing and subsequent conscious psychological processes, insofar as they determine what interest consciousness. | 0 | ||
Shevrin; Psychological Unconscious | 546 | It is hypothesized that cognitive processes outside of awareness are based on a different mode of cognition from that of conscious processes. | 0 | ||
Shevrin; Psychological Unconscious | 546 | Unconscious process is multichanneled, whereas conscious processes is single channeled. | 0 | ||
Shevrin; Psychological Unconscious | 546 | Preattentive cognition is global and gestalt in character. | 0 | ||
Shevrin; Psychological Unconscious | 546 | Multiple codes can be activated outside of awareness even though only a single code may enter consciousness. | 0 | ||
Shevrin; Psychological Unconscious | 546 | All of the models of selective attention are based, not on clinical data, but largely on experimental investigations. | 0 | ||
Shevrin; Psychological Unconscious | 546 | Percepts can be stored in long-term memory and can exert an active influence on simultaneous conscious processes. | 0 | ||
Shevrin; Psychological Unconscious | 546 | Subliminal Perception | 0 | ||
Shevrin; Psychological Unconscious | 546 | In dichotic listening experiments for selective attention, stimuli are usually presented separately to each ear. | 0 | ||
Shevrin; Psychological Unconscious | 547 | Selective attention and subliminal perception represent endpoints on a single continuum of information processing. | 1 | ||
Shevrin; Psychological Unconscious | 547 | At any given time, a person is presented with a broad array of stimuli of varying intensities and varying relevance to adaptive tasks. Selection on some basis must occur. Subliminal stimuli do not become conscious simply because they are too weak in intensity, even though they may be highly relevant. | 0 | ||
Shevrin; Psychological Unconscious | 547 | In subliminal perception, complex effects of stimuli that do not enter awareness can persist well beyond a few seconds or minutes. | 0 | ||
Shevrin; Psychological Unconscious | 547 | Subliminal perception is concerned with stimuli too weak to become conscious immediately, no matter how much attention is directed to to the stimulus. | 0 | ||
Shevrin; Psychological Unconscious | 547 | Subliminal stimuli have detectable effects on conscious processes, both immediately, and in some cases, after an interval of time. | 0 | ||
Shevrin; Psychological Unconscious | 548 | Subliminal effects emerge in changed states of consciousness, as in dreams. | 1 | ||
Shevrin; Psychological Unconscious | 548 | Subliminal stimuli can be used to explore differences between unconscious and conscious processes. | 0 | ||
Shevrin; Psychological Unconscious | 549 | In subliminal perception, the intensity of the stimulus is great enough to elicit activity in the sensory fibers but lacks sufficient energy to activate the nonspecific reticular system. Thus information reaches the cortex without awareness of the stimulus itself. | 1 | ||
Shevrin; Psychological Unconscious | 549 | Subliminal perception, according to one researcher, is made possible because the primary afferent system (which conveys sensory information to the cortex) conducts faster than the secondary, nonspecific system (which is involved in reticular activation). | 0 | ||
Shevrin; Psychological Unconscious | 549 | As a consequence of this disparity in conduction speed, it is possible for information reach the cortex and for the cortex to exert inhibitory control over the reticular system. | 0 | ||
Shevrin; Psychological Unconscious | 551 | Binocular rivalry | 2 | ||
Shevrin; Psychological Unconscious | 551 | Binocular rivalry studies offer another experimental paradigm in which cortical evoked potentials may be detected in the absence of subjective perception of the eliciting stimulus. | 0 | ||
Shevrin; Psychological Unconscious | 551 | The general procedure for binocular rivalry studies is to present different images simultaneously to the two eyes At different times, one or the other eye will be dominant. This subject will be aware of the image presented to one eye, while being unaware of the image presented to the suppressed eye. | 0 | ||

45 Mangan | 741 | Fringe experience includes virtually every feeling in consciousness that is not a sensory experience in the narrowest sense. | 0 | ||
45 Mangan | 741 | The "Aha!" experience of finding the right solution to a problem is a fringe experience (call at "rightness"), as is the opposite feeling that something is wrong, out of place, problematic ("wrongness"). | 0 | ||
45 Mangan | 741 | The term "qualia" refers to prototypically clear and vivid experiences, that are easily inspected in the focus of attention, and that belong to a specific sensory modality -- i.e. the experience of a sharp pain or the color red. | 0 | ||
45 Mangan | 741 | William James considered fringe experience to be fundamental for understanding cognition in consciousness. | 0 | ||
45 Mangan | 741 | The investigation of fringe phenomenology will tell us as much about the cognitive operation of consciousness as qualia, perhaps more. | 0 | ||
45 Mangan | 741 | The fringe itself is completely conscious. | 0 | ||
45 Mangan | 750 | Consciousness is only able to resolve itself to a certain level of detail at any given moment. | 9 | ||
45 Mangan | 750 | The capacity of consciousness is limited to about seven distinct "chunks" of experience. | 0 | ||
45 Mangan | 750 | Most of consciousness's limited resources are devoted to articulating detailed entities in focal attention. | 0 | ||
45 Mangan | 750 | Consciousness cannot possibly represent in detail anything remotely approaching the totality of information that bears on its cognitive activity. | 0 | ||
45 Mangan | 750 | The fringe is able to finesse the limited capacity of consciousness by using just a few wisps of vague experience to represent summary facts about states of non-conscious information that are otherwise far too complex for direct conscious representation. | 0 | ||
45 Mangan | 753 | Information experienced inattentively is still conscious, although it lacks the overall specifiable organization we find in an object in the focus of attention. | 3 | ||
