Reactions of 252 neurons of the mediodorsal nucleus (MD) and 329 cells of the pulvinar-posterior-lateral complex (Pulv-LP) of the thalamus to separate the complex peripheral stimulations (visual, auditory and somatosensory) were studied in acute experiments on cats anaesthetized with a mixture of chloralose and nembutal. According to the character of the neuronal responses to peripheral stimuli three types of reactions were found: acceleration of the background activity (32.0% neurons in Pulv-LP and 20.6% in MD), inhibition (21.0% neurons in Pulv-LP and 24.2% in MD) and mixed (8.8% neurons in Pulv-LP and 4.0% in MD). No responses were observed in 37.4% neurons of Pulv-LP and in 51.2% of MD. Along with certain similarity, some specific features in the organization of Pulv-LP and MD were found. According to the response latency, the neuronal reactions to stimulation were divided into three groups: with short (less than 20 ms), medium (21--40 ms) and long (over 41 ms) latent period. The second group was the most numerous.
在使用水合氯醛和戊巴比妥混合物麻醉的猫的急性实验中，研究了丘脑内侧背核（MD）的252个神经元和丘脑后外侧复合体（Pulv-LP）的329个细胞对复杂外周刺激（视觉、听觉和躯体感觉）的反应。根据神经元对外周刺激的反应特征，发现了三种反应类型：背景活动加速（Pulv-LP中32.0%的神经元，MD中20.6%的神经元）、抑制（Pulv-LP中21.0%的神经元，MD中24.2%的神经元）和混合反应（Pulv-LP中8.8%的神经元，MD中4.0%的神经元）。Pulv-LP中37.4%的神经元和MD中51.2%的神经元未观察到反应。除了某些相似性外，还发现了Pulv-LP和MD组织中的一些特定特征。根据反应潜伏期，神经元对刺激的反应分为三组：潜伏期短（小于20毫秒）、中等（21-40毫秒）和长（超过41毫秒）。第二组数量最多。
