Consciousness
Allan Hobson
Presents waking consciousness, sleep and dreaming as different global states of the same brain, distinguished by which neuromodulatory systems are active.

Surveys what neurology's loss-of-consciousness cases - coma, seizure, sleep, anaesthesia - reveal about what consciousness requires from the brain.
Anil Seth (TED)
Argues that perception is a controlled hallucination in which the brain's predictions are corrected by sensory error rather than built up from it, and extends the account to the sense of self.

Argues chronic sleep loss causes measurable harm across memory, immunity and mood, a popular synthesis later disputed for overstating the certainty of some of the underlying evidence.
Eugene Aserinsky & Nathaniel Kleitman
Reports periodic bursts of rapid eye movement during sleep accompanied by a distinct EEG pattern, identifying REM as a physiologically separate sleep stage.

Proposes dreams arise when the forebrain synthesises a narrative from essentially random brainstem activation during REM sleep, rather than expressing a disguised unconscious wish.
Charles Czeisler et al.
Shows the human circadian pacemaker runs close to 24 hours rather than the longer period long assumed from earlier studies confounded by artificial light exposure.
Roland Griffiths, William Richards, Una McCann & Robert Jesse
Reports that a single high dose of psilocybin under controlled conditions occasions experiences volunteers rate as among the most meaningful of their lives, restarting clinical research into psychedelics.

Argues general anaesthetics produce unconsciousness by disrupting communication between brain regions rather than by silencing any single centre.

Shows psilocybin reduces activity and connectivity in the brain's default mode network hubs, arguing the psychedelic state results from disintegration rather than increased brain activity.
Allan Rechtschaffen & Anthony Kales
Establishes a standardised system for scoring human sleep stages from EEG, EOG and EMG that made sleep research results comparable across laboratories.

Proposes consciousness arises when information is broadcast from a limited-capacity global workspace to many specialised unconscious processors at once.
This subject genuinely sits in more than one domain. These fields approach the same ground with different methods.
