Rolls; Emotion Explained 1 What are emotions?  Why do we have emotions?  What is their adaptive value?  What are the brain mechanisms of emotion, and how can disorders of emotion be understood?  Why does it feel like something to have an emotion?  Why do emotions sometimes feel so intense? 1
Rolls; Emotion Explained 1 Emotion and motivation are linked by the property that both involve rewards and punishers. 0
Rolls; Emotion Explained 1 Emotions can be thought of as states elicited by rewards or punishers. 0
Rolls; Emotion Explained 1 Motivation can be thought of as a state in which a reward is being sought, or a punisher is being avoided or escaped from. 0
Rolls; Emotion Explained 1 Importance of reward and punishment for emotion and motivation. 0
Rolls; Emotion Explained 2 Some stimuli are innately rewarding or punishing and are called primary reinforcers. 1
Rolls; Emotion Explained 2 No learning is necessary to respond to pain as aversive. -- Pain is a primary reinforcer. 0
Rolls; Emotion Explained 2 Stimulus-reinforcement association learning. 0
Rolls; Emotion Explained 3 Autonomic responses are those mediated through the autonomic nervous system, via the vagus and sympathetic nerves, which affect smooth muscle. 1
Rolls; Emotion Explained 4 Many endocrine (hormonal) responses are mediated through the autonomic nervous system and are autonomic responses, for example the release of adrenaline (epinephrine) from the adrenal gland during emotional excitement. 1
Rolls; Emotion Explained 4 Previously neutral stimuli can by pairing with unconditioned stimuli come by learning the association to produce learned autonomic responses. -- Classical Conditioning 0
Rolls; Emotion Explained 4 Classical conditioning is very similar to stimulus-reinforcer    association learning, except that in the case of classical conditioning the responses involved are autonomic and endocrine responses. 0
Rolls; Emotion Explained 4 Motivation refers to the state an animal is the and when it is willing to work for a reward or to escape from or avoid a punisher. 0
Rolls; Emotion Explained 7 For both emotion and motivation,    rewards and punishers    are assessed    in order to provide the goals for behavior. 3
Rolls; Emotion Explained 7 Computing the reward and punisher value    of sensory stimuli,    and then using selection between    different rewards    and avoidance of punishers    in a common reward-based currency    appears to be the fundamental design that brains use    in order to produce appropriate behavior. 0
Rolls; Emotion Explained 7 Having reward and punishment systems is the solution that evolution has developed to produce appropriate behavior. 0
Rolls; Emotion Explained 11 Proposed definition of emotions -- emotions    are states elicited by    rewards and punishers. 4

Rolls; Emotion Explained 84 An important question for understanding brain function is whether a particular object, (or face) is represented in the brain by the firing of one or a few gnostic (or 'grandmother') cells,    or whether instead the firing of a group or ensemble of cells    each with somewhat different responsiveness    provides the representation. 6

Rolls; Emotion Explained 149 Associative processes    involved in emotion-related learning 0
Rolls; Emotion Explained 150 Pavlovian or Classical Conditioning 1
Rolls; Emotion Explained 155 Connections of the amygdala 5
Rolls; Emotion Explained 155 The amygdala is a subcortical region of the anterior part of the temporal lobe. 0
Rolls; Emotion Explained 155 The amygdala receives massive projections from the overlying temporal lobe cortex. 0
Rolls; Emotion Explained 155 Inputs to the amygdala come from higher stages of sensory processing    in the visual and auditory modalities,    and not from early cortical processing areas. 0
Rolls; Emotion Explained 155 The amygdala also receives inputs that are potentially about primary reinforcers,   e.g. taste inputs (from the secondary taste cortex,    via connections from the orbitofrontal cortex to the amygdala),    and somatosensory inputs,    potentially about the rewarding or painful aspects of touch (from the somatosensory cortex via the insula). 0
Rolls; Emotion Explained 155 The amygdala also receives projections from the posterior orbitofrontal cortex. 0
Rolls; Emotion Explained 155 Subcortical inputs to the amygdala include projections from the midline thalamic nuclei, the subiculum, CA1 parts of the hippocampal formation, and the hypothalamus. 0
Rolls; Emotion Explained 156 Emotions are usually elicited by environmental stimuli analyzed to the object level, and not to retinal arrays. 1
Rolls; Emotion Explained 157 Outputs of the amygdala include the well-known projections to the hypothalamus. 1
Rolls; Emotion Explained 157 The amygdala has back projections to many areas of the temporal, orbitofrontal, and insula cortices from which it receives inputs. 0
Rolls; Emotion Explained 161 There are separate output pathways from the amygdala    for different fear related responses. 4
Rolls; Emotion Explained 163 One output system of the amygdala is to the nucleus accumbens, a part of the striatum. 2
Rolls; Emotion Explained 163 The core part of the nucleus accumbens is part of the pathway for approach responses to conditioned stimuli. 0
Rolls; Emotion Explained 164 Consistently, dopamine release   in the core part of the nucleus accumbens   is increased    by conditioned emotional stimuli,    both appetitive and aversive. 1
Rolls; Emotion Explained 164 Amygdala is involved in responses    made to stimuli that are associated by learning    with primary reinforcers, including rewards as well as punishers. 0
Rolls; Emotion Explained 164 Amygdala is a brain region for stimulus-reinforcer association learning. 0
Rolls; Emotion Explained 164 The amygdala has partly dissociable systems    for Pavlovian effects implemented via the central nucleus, and for effects of affective representations implemented via the basolateral amygdala. 0

Rolls; Emotion Explained 191 Basal Forebrain Cholinergic Neurons 0
Rolls; Emotion Explained 194 Noradrenergic Neurons 3
Rolls; Emotion Explained 194 Effects of emotion on cognitive processing and memory. 0
Rolls; Emotion Explained 195 Whenever memories are stored,    part of the context    is stored with the memory.    This is very likely to happen in associative neuronal networks    such as those in the hippocampus. 1
Rolls; Emotion Explained 195 The CA3 part of the hippocampus may operate as a single associative memory capable of linking together almost arbitrary co-occurrences of inputs, including inputs about emotional state that reach the entorhinal cortex from the amygdala. 0
Rolls; Emotion Explained 195 Recall of a memory occurs best in associative networks    when the input key to the memory    is nearest to the original input pattern of activity that was stored. 0
Rolls; Emotion Explained 195 Recall from the hippocampus    is likely to use the highly developed back projections    from the hippocampus to the neocortex. 0
Rolls; Emotion Explained 195 The hippocampus, which is implicated in in memory of past episodes, contains neurons that respond to combinations of spatial information and reward information. 0
Rolls; Emotion Explained 196 The ability to form associations between events including where they occur and what is present is the fundamental property of episodic memory. 1
Rolls; Emotion Explained 196 The primate anterior hippocampus receives inputs from    brain regions involved in reward processing    such as the amygdala and orbitofrontal cortex. 0
Rolls; Emotion Explained 197 Hippocampus may store information about    where emotion-related events happened;    may take part in the recall of emotions    when particular places are seen again;    and may provide a system in which the current mood    can influence which memories are recalled. 1
Rolls; Emotion Explained 197 Effects of mood    on storage and recall    could be facilitated by the back projection    from structures important in emotions    such as the amygdala and orbitofrontal cortex    to parts of the cerebral cortex important in representation of objects,    such as the inferior temporal visual cortex. 0
Rolls; Emotion Explained 198 Co-activity between forward inputs and back projections    could result in facilitation or recall of cortical representations (e.g. particular faces)    that had become associated with emotional states, represented by activity in the amygdala. 1
Rolls; Emotion Explained 198 Theory of how effects of mood    on memory and perception    could be implemented in the brain.     Massive projections from parts of the brain where mood is represented,    such as the orbitofrontal cortex and amygdala,    to the cortical areas such is the inferior temporal visual cortex and hippocampus-related areas    that project into these mood-representing areas. 0

Rolls; Emotion Explained 260 Inferior Temporal Visual Cortex 1
Rolls; Emotion Explained 322 Basal ganglia are parts of the brain that include the striatum,    globus pallidus,    substantia nigra,    and subthalamic nucleus,    and are necessary for the normal initiation of movement. 62
Rolls; Emotion Explained 322 Depletion of the dopaminergic input to the striatum    leads to the lack in the initiation    of voluntary movement    that occurs in Parkinson's disease. 0
Rolls; Emotion Explained 322 Basal ganglia receive inputs    from all parts of the cerebral cortex,    including the motor cortex,    and have outputs directed strongly toward the premotor and prefrontal cortex    via which they could influence movement initiation. 0
Rolls; Emotion Explained 322 The general connectivity of the basal ganglia    is for cortical and limbic inputs    to reach the striatum,    which then project to the globus pallidus and substantia nigra pars reticulata,    which in turn project via the thalamus back to the cerebral cortex. 0
Rolls; Emotion Explained 322 Within the overall scheme of basal ganglia connectivity,    there is a set of at least partially segregated parallel processing streams. 0
Rolls; Emotion Explained 323 There is evidence linking the ventral striatum and its dopamine input to reward. 1
Rolls; Emotion Explained 324 Rats will self-administer amphetamines into the nucleus accumbens,    and lesions of the nucleus accumbens    attenuate the intravenous self-administration of cocaine. 1
Rolls; Emotion Explained 325 Lesions of the dopamine pathways that deplete the striatum of dopamine lead to a failure to orient to stimuli,    a failure to initiate movements,    catalepsy,    and a failure to eat and drink. 1
Rolls; Emotion Explained 325 In humans, depletion of dopamine in the striatum    is found in Parkinson's disease,    in which there is akinesia (i.e. a lack of voluntary movement),    bradykinesia (slow movement),    rigidity,    and tremor. 0
Rolls; Emotion Explained 338 The activity of many neurons in the putamen is related to movements. 13
Rolls; Emotion Explained 338 There is a somatotopic organization of neurons in the putamen,    with separate areas containing neurons responding    to arm, leg, or orofacial movements. 0
Rolls; Emotion Explained 338 The firing rate of neurons in the putamen    tends to be linearly related    to the amplitude of movements. 0
Rolls; Emotion Explained 338 Patients with basal ganglia disease frequently have difficulty in controlling the amplitude of their limb movements. 0
Rolls; Emotion Explained 339 What computations are performed by the basal ganglia? 1
Rolls; Emotion Explained 340 The striatum would be particularly involved in the selection of behavioral responses,    and producing one coherent stream of behavioral output,    with the possibility to switch to a different behavior    if a higher priority input is received. 1
Rolls; Emotion Explained 340 The selection of behavioral responses may be achieved by laterally spreading competitive interaction between striatal or palatal neurons. 0
Rolls; Emotion Explained 340 Inhibitory interneurons within the striatum may play a part in the interaction between striatal processing streams. 0
Rolls; Emotion Explained 342 A behavioral selection function between processing streams in the basal ganglia,    even without any convergence anatomically between processing streams,    might provide an important computational rationale for the basal ganglia. 2
Rolls; Emotion Explained 345 The basal ganglia may be able to detect combinations of conjunctively active inputs    from quite widespread regions of the cerebral cortex    using their combinatorial architecture and a property of synaptic modifiability.    In this way it would be possible to trigger any complex pattern    of behavioral responses    by any complex pattern    of environmental inputs,    using what is effectively an associative network. 3
Rolls; Emotion Explained 347 Dopamine may play an important role in setting the thresholds of striatal neurons. 2
Rolls; Emotion Explained 347 Dopamine neurons could not convey information about a primary reward obtained if the trial is successful, in the way that orbitofrontal cortex neurons do. 0
Rolls; Emotion Explained 388 Pheromones can cause groups of women housed together to start cycling together. 41
Rolls; Emotion Explained 400 We may build a computer that would perform the functions of the emotions, yet we may not want to ascribe emotional feelings to the computer. 12
Rolls; Emotion Explained 400 We may think that the most important aspect of emotions is feelings and that their neural basis has not been accounted for. 0
Rolls; Emotion Explained 400 How do the emotional feelings and sensory events come to feel like anything? These 'feels' are called qualia. They are great mysteries that have puzzled philosophers for centuries. 0
Rolls; Emotion Explained 401 Many actions can be performed relatively automatically, without apparent conscious intervention, i.e. driving a car. 1
Rolls; Emotion Explained 401 Actions that are relatively automatic could involve control of behavior by brain systems that are old in evolutionary terms such in the basal ganglia. 0
Rolls; Emotion Explained 401 The basal ganglia and cerebellum do not have backprojection systems to most of the parts of the cerebral cortex from which they receive inputs. 0
Rolls; Emotion Explained 401 Parts of the brain such as the hippocampus and amygdala involved in such functions as episodic memory and emotion, do have major backprojection systems to the high parts of the cerebral cortex from which they receive forward projections. 0
Rolls; Emotion Explained 401 It may be that evolutionarily newer parts of the brain, such as the language areas and parts of the prefrontal cortex, are involved in an alternative type of control of behavior, in which actions can be planned with the use of a language system that allows relatively arbitrary syntactic manipulation of semantic symbolic entities. 0
Rolls; Emotion Explained 401 The general view that there are many routes to behavioral output is supported by the evidence that there are many input systems to the basal ganglia (from almost all areas of the cerebral cortex), and that neuronal activity in each part of the striatum reflects the activity in the overlying cortical area. 0
Rolls; Emotion Explained 401 The language areas offer one of many routes to action, but a route particularly suited in planning actions, because of the syntactic manipulation of semantic entities, which may make the long-term planning possible. 0
Rolls; Emotion Explained 403 General view of brain evolution and which, as areas of the cortex evolved, they are laid on top of the existing circuitry connecting inputs to outputs, and in which each level in this hierarchy of separate input and output data pathways may control behavior are according to the specialized function it can perform. 2
Rolls; Emotion Explained 403 Mathematicians may get a hunch that something is correct, yet not be able to verbalize why. They may then resort to formal, more serial and language-like theorems to prove the case, and these seem to require conscious processing. 0
Rolls; Emotion Explained 427 The ventral visual system is concerned with selecting goals for action. It does this by providing invariant representations of objects, with a representation that is appropriate for interfacing to systems such as the amygdala and orbitofrontal cortex. 24
Rolls; Emotion Explained 427 The dorsal visual system helps with executing actions, for example in shaping the hand appropriately to pick up a selected object. Often the sensori-motor operation is performed implicitly, i.e. without conscious awareness. 0
Rolls; Emotion Explained 427 Insofar as explicit planning about future goals and actions requires knowledge of objects and their reward or punisher associations, it is the ventral visual system that provides the appropriate input for planning future actions. 0
Rolls; Emotion Explained 427 When explicit, or conscious, planning is required, activity in the ventral visual system will be closely related to consciousness. 0
Rolls; Emotion Explained 427 It is to objects are represented in the ventral visual system that we normally apply multistep planning processes. 0
Rolls; Emotion Explained 428 The outputs of the reward and punishment systems must be treated by the action system as being the goals for action. 1
Rolls; Emotion Explained 428 The action systems must be built to try to maximize the activation of the representations produced by rewarding events, and to minimize the activation of the representations produced by punishers or stimuli associated with punishers. 0
Rolls; Emotion Explained 429 The architectural design principles of the brain to the stage of the representation of rewards and punishers and thus of emotion seems apparent. 1
Rolls; Emotion Explained 429 How the brain selects between reward and punishment signals how the cost of actions are taken into account, and how actions are selected remain to be determined. 0
Rolls; Emotion Explained 454 Neural network simulation of biologically plausible pattern association memories such as may be present in orbitofrontal cortex and amygdala and autoassociation or attractor networks. 25
