Responses of single hypothalamic neurons to splanchnic, sciatic nerves and photic stimulation were studied in anesthetized, curarized cats. It is found that units of the posterior and anterior hypothalamus are "convergence neurons" with multisensory inputs. Convergence of somatosensory and visceral (splanchnic) impulses to such neurons was complete. No neurons responding only to the splanchnic nerve stimulation were found. In the posterior hypothalamus some units responded only to stimulation of splanchnic and sciatic nerves and were unresponsive to a flash. On the contrary, in the anterior hypothalamus a part of units responded only to photic stimulation. The polysensory neurons of the posterior and anterior hypothalamus were of a nonspecific modality: they responded with a similar pattern of phasic or tonic discharge with a predominance of phasic responses. Units were more often excited than inhibited. A high responsibility (68%) of spontaneously active neurons to somato-visceral and photic stimulation was observed in the posterior, as well as in the anterior hypothalamus. The principles of functional organization of hypothalamic afferent system are discussed.
在麻醉、箭毒化的猫身上研究了单个下丘脑神经元对内脏神经、坐骨神经和光刺激的反应。发现下丘脑前后部的神经元是具有多感觉输入的“汇聚神经元”。躯体感觉和内脏（内脏神经）冲动对这类神经元的汇聚是完全的。未发现仅对内脏神经刺激有反应的神经元。在下丘脑后部，一些单位仅对内脏神经和坐骨神经刺激有反应，对闪光无反应。相反，在下丘脑前部，一部分单位仅对光刺激有反应。下丘脑前后部的多感觉神经元具有非特异性模式：它们以相似的相位或紧张性放电模式反应，以相位反应为主。单位通常被兴奋而非抑制。在下丘脑后部以及前部，观察到自发活动神经元对躯体-内脏和光刺激的高反应性（68%）。讨论了下丘脑传入系统功能组织的原则。
