[Local temperature characteristics of the isolated cortex in wakefulness and alteration of the sleep stages].
In cats, changes of the brain electric activity were followed by local temperature shifts in isolated and in intact cortex: the transition from slow wave sleep to paradoxical sleep and from quiet to active wakefulness were accompanied by increasing of the cortex temperature, while transition from paradoxical sleep to slow sleep decreased the temperature. During falling asleep and alternation of the sleep stages, both in isolated and intact cortex, the temperature shifts preceded the electric activity changes. The temperature of isolated cortex is by 0.2 degrees lower than that of the opposite intact hemisphere.
