Data derived from several studies were taken to determine the time course of Process S during both wakefulness and sleep. As required by the model, slow-wave-sleep (SWS; an index of Process S) was(More)

One implication of this hypothesis is that a phase delay of sleep in normal subjects should produce the same abnormalities of REM sleep.(More)
