Abstract

The reactions of neurons of the associative mediodorsal nucleus of the thalamus to a solitary stimulation of the radial, sciatic, and splanchnic nerves were studied in conditions of an acute experiment in anesthetized and immobilized cats. There were 91.85, 90.56, and 81.35% reactive neurons, respectively. They were mainly concentrated in the parvocellular division of the nucleus. A high degree of convergence (82.6%) of somatic and visceral signals was found and their interaction was of the reciprocal blocking type.

摘要

在对麻醉并固定的猫进行的急性实验条件下,研究了丘脑联合内侧背核神经元对桡神经、坐骨神经和内脏神经的单次刺激的反应。反应性神经元分别为91.85%、90.56%和81.35%。它们主要集中在该核的小细胞部。发现躯体和内脏信号高度汇聚(82.6%),且它们的相互作用属于相互阻断类型。
