摘要

该工作对35只家兔在背侧海马区用玻璃微电极记录了103个神经元单位放电,分类如下:56个神经元属非呼吸节律性自发的间歇性放电,可分为两种类型:一为长时振荡型放电;另一为短时振荡型放电。47个神经元出现呼吸节律同步性自发放电,可分为三种类型:吸气型15个单位;呼气型9个单位;跨时相型23个单位。上述结果提示:边缘系统海马的呼吸信息在情绪活动的协调方面可能是一个有趣的问题。

Abstract

In dorsal hippocampus of 35 rabbits, unit discharges of 103 neurons were recorded by glass microelectrodes and classified as follows: Spontaneous intermittent discharges not related to respiratory rhythm were observed in 56 neurons,which could be divided into two types,respectively characterized by long time and short time oscillations. Spontaneous discharges with respiratory rhythm were observed iri 47 neurons, which could be divided into 3 types, namely, inspiratory type (n=15), expiratory type (n=9), and phase-spanning respiratory type (n=23). The results mentioned above might suggest that the respiratory information on to the hippocampus of the limbic system is an interesting problem in the coordination of emotional activities.
