Abstract

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.

摘要

在猫身上,孤立的和完整的皮层中脑电活动的变化伴随着局部温度的变化:从慢波睡眠到异相睡眠以及从安静觉醒到主动觉醒的转变都伴随着皮层温度的升高,而异相睡眠到慢波睡眠的转变则会使温度降低。在入睡和睡眠阶段交替期间,无论是在孤立的还是完整的皮层中,温度变化都先于电活动变化。孤立皮层的温度比相对的完整半球低0.2摄氏度。
