Abstract
THE cyclic nature of sleep in mammals, including the regular recurrence of a state characterized by a low voltage desynchronized electroencephalogram, rapid eye movements, and heightened autonomic activity, is now firmly established1,2. This state, associated in humans with dreaming, has been called “dreaming state”, “rapid eye-movement sleep” or “paradoxical sleep”, and we refer to it as the “D-state”3.
