Hobson; Dream Drugstore 57 Physiological basis of differences between waking and dreaming. -  (table) 5
Hobson; Dream Drugstore 58 During visual hallucinations, endogenous perceptions arise at high levels of visual processing. 1
Hobson; Dream Drugstore 59 Dreaming; integration of vision with other sensory modalities, hyperactivity of the parietal operculum, where vision, space, and movement meld. 1
Hobson; Dream Drugstore 61 Dreaming; vivid hallucinations and exaggerated emotions - brain hyperactivity, visual associative cortex (dream hallucinations); amygdala (fear, elation, anger). 2
Hobson; Dream Drugstore 63 Diminished serotonergic and noradrenergic modulation in sleep; chemicals essential to recent memory processes, down 50 percent in NREM sleep and nearly 100 percent in REM. 2
Hobson; Dream Drugstore 63 Any exogenous chemical that interfered with either norepinephrine or serotonin (or glutamate and dopamine) might be expected to introduce dreamlike discontinuity and incongruity into waking consciousness. 0
Hobson; Dream Drugstore 63 Dorsolateral prefrontal cortex, crucial for working memory - substrate of volition and of planning, while the medial and orbitofrontal regions appear to mediate social judgment and insight. 0
Hobson; Dream Drugstore 64 In REM sleep the emotional brain (amygdala) is hyperactive. The executive brain (frontal cortex) is hypoactive. 1
Hobson; Dream Drugstore 65 Aminergic systems support fight-and-flight responses, vasoconstriction, and direct flow to the muscles. 1
Hobson; Dream Drugstore 65 Cholinergic systems promote rest and recovery. 0
Hobson; Dream Drugstore 65 Aminergic and cholinergic neuromodulatory neurons in the subcortical brain. 0
Hobson; Dream Drugstore 69 Psychoanalysis was founded by Sigmund Freud in 1900. 4
Hobson; Dream Drugstore 71 Dreaming is an altered state of consciousness, akin to those induced by psychedelic drugs in waking. 2
Hobson; Dream Drugstore 71 Brain stores its own drugs and releases them depending on the brain's state. 0
Hobson; Dream Drugstore 71 Why are dreams so bizarre?    Without norepinephrine and serotonin,    the cerebral cortex and hippocampus create odd and remote associations.    Dreams are therefore inherently and primarily bizarre. 0
Hobson; Dream Drugstore 71 Dreams    are dripping with emotional salience,    even when they are cognitively delirious. 0
Hobson; Dream Drugstore 79 People dream    at least 90 minutes per night (and probably much more). 8
Hobson; Dream Drugstore 79 With the memory molecules norepinephrine and serotonin locked up in the 'Dream Drugstore'    and with the working memory circuits in the frontal cortex greatly attenuated,    no record of dreaming    is ever entered into memory. 0
Hobson; Dream Drugstore 84 There is no clear evidence    that psychedelic chemicals    do any permanent harm. 5
Hobson; Dream Drugstore 88 Dissociation    is the separation of modules of consciousness    that are usually associated with one another. 4
Hobson; Dream Drugstore 88 There is the usual association    of perception and movement    with memory and conscious awareness. 0
Hobson; Dream Drugstore 88 Consciousness    is best conceived as the brain's awareness of its own activity,    including such modular functions as perception, memory, thinking, and feeling,    each of which has some degree of anatomical localization    or functional specialization. 0
Hobson; Dream Drugstore 88 For conscious states to be fully associated --    that is characterized by a unified and internally consistent set of properties --    the several anatomical and physiological substrates    of each of the several component modules    must be perfectly synchronized and perfectly integrated. 0
Hobson; Dream Drugstore 91 Because REM sleep    is fraught with dissociative phenomena   (e.g. amnesia, hallucinations, bizarre mentation, anxiety, and loss of volitional control),    we focus on some of the properties of the unique neuronal population of the brain stem cholinergic system. 3
Hobson; Dream Drugstore 91 Do highly hypnotizable people    possess inherited or learned hypersensitivity of the cholinergic system    such that shifts to a dreamlike state    are precipitated directly out of waking? 0
Hobson; Dream Drugstore 92 What we call intuition    is, in fact, the tuning in of emotion-based conscious processing    and the tuning out of logical operations. 1
Hobson; Dream Drugstore 92 Gut feelings    are so named because they are the metaphor and the conscious experience of involuntary autonomic nervous system activation    like stomach churning, rapid heart action, and sweating    that are automatically triggered by the limbic system    when a stimulus generates fear and anxiety. 0
Hobson; Dream Drugstore 93 Lucid Dreaming 1
Hobson; Dream Drugstore 93 The rare but learnable talent of lucid dreaming    can be defined as the bolstering of the self reflective awareness    that is normally diminished or absent in dreaming. 0
Hobson; Dream Drugstore 95 Alter consciousness voluntarily    and without the use of drugs    to achieve many of the formal desiderata    of the drug-induced psychedelic states. 2

Hobson; Dream Drugstore 123 Thalamocortical system 21
Hobson; Dream Drugstore 176 Most neurocognitivists believe that conscious experience arises in the forebrain    with participation of widely distributed but interconnected circuits    in the neocortex and in subcortical centers like the basal ganglia and limbic structures.  [thalamocortical system]  [Edelman's dynamic core] 53
Hobson; Dream Drugstore 176 Most neurocognitivists believe that the distributed and interconnected cortical circuits that are the physical substrate of conscious experience need to be synchronously activated, probably by the widely distributed thalamocortical system.  [Edelman's dynamic core] 0
Hobson; Dream Drugstore 176 Most neurocognitivists believe that the source of activation of the thalamocortical system and the distributed forebrain circuits underlying consciousness is the brainstem reticular formation, and especially its pontine-mesencephalic and diencephalic components, which regulate the cortex via its interaction with the thalamocortical system. 0
