Abstract

Unit activity in the substantia nigra pars reticulata was recorded during monkey bar-press feeding behavior. Activity of one-third of neurons was related to motor execution such as arm extension, flexion and bar-pressing, but not to motor preparation. Motor-related neurons were distributed mainly in the rostrolateral part of the nucleus. More than one-third responded during feeding and/or drinking acts and to intra- or perioral sensory stimuli. These ingestion-related neurons were distributed mainly in the caudomedial part of the nucleus.

摘要

在猴子按压杠杆取食行为期间，记录黑质网状部的单位活动。三分之一神经元的活动与诸如手臂伸展、弯曲和按压杠杆等运动执行相关，但与运动准备无关。与运动相关的神经元主要分布在核的 rostrolateral 部分。超过三分之一的神经元在进食和/或饮水行为期间以及对口内或口周感觉刺激有反应。这些与摄食相关的神经元主要分布在核的 caudomedial 部分。（注：rostrolateral 和 caudomedial 这两个专业术语可能有更准确的中文表述，这里直接保留英文以便更准确传达原文意思，具体准确的中文表述可根据医学专业知识进一步确定）
