Chronic experiments were carried out on nonanesthetized cats. A study was made of peculiarities attending the transmission of the afferent signals and the following inhibitory processes in the posterior ventral nucleus of the thalamus, depending on the state of sleep and wakefulness. Transmission of the signals decreases during the dreaming condition and the slow-wave sleep, and increases during the active states of alert cats. In paradoxical sleep the signal transmission is at the same level as such at resting wakeful condition. A marked transmission fluctuation is seen during the dreaming state and in the course of the first phase of sleep. The level of signal transmission is the most stable during the active states. The degree of the trance inhibitory process after the afferent signal transmission depends on the level of anesthesia, wakefulness and natural sleep. Processes following the afferent signal transmission in the posterior ventral nucleus of the thalamus show a radical difference in the barbituiate-anesthetized in comparison with nonanesthetized animals. The trace inhibition, so characteristic of anesthesia, was expressed in the dreaming state of the animal but insignificantly; in the wakeful condition it is not manifested at all.
在未麻醉的猫身上进行了慢性实验。研究了丘脑后腹核中传入信号的传递以及随后的抑制过程的特点，这取决于睡眠和清醒状态。在做梦状态和慢波睡眠期间，信号传递减少，而在警觉猫的活跃状态下增加。在异相睡眠中，信号传递与静息清醒状态时处于同一水平。在做梦状态和睡眠第一阶段过程中可见明显的传递波动。在活跃状态下，信号传递水平最稳定。传入信号传递后痕迹抑制过程的程度取决于麻醉、清醒和自然睡眠的水平。与未麻醉动物相比，丘脑后腹核中传入信号传递后的过程在巴比妥类麻醉动物中表现出根本差异。麻醉所特有的痕迹抑制在动物的做梦状态中有所表现，但不明显；在清醒状态下则根本不表现。
