Abstract

Responses of single hypothalamic units to stimulation of the vagal, splanchnic and sciatic nerves and to photic stimulation were studied in anaesthetized, curarized cats. Most of the reactive neurons of the posterior and anterior hypothalamus responded to stimulation of vagus and splanchnicus. The pattern of responses of these polysensory units reactive in most cases to sciatic nerve and (or) photic stimulation too, were mainly unidirectional, nonreciprocal and excitatory in case of stimulation of visceral afferents of parasympathetic and sympathetic nerves. Absence of reciprocal responses to stimulation of "antagonistic" autonomic nerves and predominance of "convergence" units with polysensory inputs suggest that the electrical reaction of most of posterior as well as anterior hypothalamic neurons are of nonspecific "reticular" type.

摘要

在麻醉、箭毒化的猫身上,研究了单个下丘脑单位对迷走神经、内脏神经和坐骨神经刺激以及光刺激的反应。下丘脑前后部的大多数反应性神经元对迷走神经和内脏神经的刺激有反应。这些多感觉单位在大多数情况下对坐骨神经和(或)光刺激也有反应,其反应模式主要是单向的、非交互性的,并且在刺激副交感神经和交感神经的内脏传入神经时是兴奋性的。对“拮抗”自主神经刺激缺乏交互反应以及具有多感觉输入的“汇聚”单位占优势,表明下丘脑前后部的大多数神经元的电反应属于非特异性的“网状”类型。
