The responses of anterior hypothalamic-preoptic units to direct thermal stimulation were studied during wakefulness and sleep in cats. Seventy-nine percent of the selected units showed changes in firing rate in relation to wakefulness and sleep stages. Forty-nine percent of the units characterized by activity related to EEG patterns were found to be responsive to thermal stimulation in wakefulness and synchronized sleep. Unit responses to thermal stimulation were either absent or inconsistent in desynchronized sleep.
研究了猫在清醒和睡眠状态下下丘脑视前区前部神经元对直接热刺激的反应。所选取的神经元中有79%的放电频率随清醒和睡眠阶段发生变化。在以与脑电图模式相关的活动为特征的神经元中，有49%被发现对清醒和同步睡眠状态下的热刺激有反应。在去同步睡眠状态下，神经元对热刺激的反应要么缺失，要么不一致。
