Document Summary
From n1 to rem the reports are consistent with a progressive shut out from the environmental inputs - higher response/arousal threshold. N1, 80-90% of time, when waken up, sleepers report hypnagogic hallucinations (snapshots or still frames). Wake(cid:374) up fro(cid:373) nrem, sleepers" reports do (cid:374)ot i(cid:374)di(cid:272)ate i(cid:373)ages (cid:271)ut (cid:862)thought-like(cid:863) (cid:272)o(cid:374)te(cid:374)t, especially early in night/sleep more dream-like as night goes on. Rem: most reports are of typical dreams rich in modality-specific vivid images, mostly visual but also including the other senses. 1) information availability availability in the local neural activity states. 2) information integration activity must be integrated. In wakefulness; 1 and 2 are always achieves. In n1 and rem; little interference / suppression of integration. In nrem sweep of slow waves in downstate disrupts 1 and 2 with local disconnections and with a global down state. Neurological model of dreaming: matches dreaming phenomenology to brain activity patterns.
