Using a single unit recording technique in freely moving Cats, we have demonstrated the presence of two groups of neurons in the ventrolateral part of the caudal hypothalamus. One is characterized by a tonic discharge during waking and paradoxical sleep, the other is highly selective to the waking state. This group of neurons showed a slow tonic and regular discharge during wakefulness, a significant decrease in firing rate during stage I slow-wave sleep and a complete cessation of firing during stage II slow-wave sleep and subsequent paradoxical sleep.
运用单单元记录技术，在自由活动的猫身上，我们已证实在下丘脑尾部腹外侧部分存在两组神经元。一组的特征是在清醒和异相睡眠期间呈现紧张性放电，另一组则对清醒状态具有高度选择性。这组神经元在清醒时表现为缓慢的紧张性和规则放电，在I期慢波睡眠期间放电频率显著降低，在II期慢波睡眠及随后的异相睡眠期间放电完全停止。
