Abstract
Sleep, accompanied by slow waves in the EEG (orthosleep), does not lead to any marked alterations of the cerebral oxygen uptake or blood flow in man [7]. In dogs, however, a slight reduction of the cortical blood flow and oxygen uptake has been demonstrated during the same form of sleep [6]. Paradoxical sleep (parasleep) accompanied by a fast EEG rhythm and periods of rapid eye movements (REMs) leads, however, to an increase of the cerebral circulation as demonstrated with a thermoelectric technique [1, 5]. This finding has recently been confirmed by Reivich [8], with a quantitative autoradiographic rCBF-technique. Cooper and Hulme [3], found an increase of the intracranial pressure during REM sleep, probably caused by an increase of cerebral blood flow and blood volume (see below).
