Abstract

The influence of the electrical stimulation of the dorsolateral (DL) and the ventromedial (VM) portions of the caudal area of the mesencephalic reticular formation on the neuronal activity of the lateral zone of the gyrus sygmoideus posterior was investigated in cats. The mesencephalo-cortical influences were mainly excitatory in character; the predominance of the neuronal reactions with a short latency (3--12 msec) during the VM stimulation and reactions with a longer latency (20--25 msec) during the DL stimulation was revealed. The VM and the DL were found to influence both cortical neurones, the ones sensitive to somesthetic stimuli (mono-, di- and polyvalent) and the ones which failed to respond to the electrocutaneous stimulation of the limbs.

摘要

在猫身上研究了中脑网状结构尾部背外侧(DL)和腹内侧(VM)部分的电刺激对后扣带回外侧区神经元活动的影响。中脑-皮质的影响主要是兴奋性的;发现在VM刺激期间潜伏期短(3-12毫秒)的神经元反应占优势,而在DL刺激期间潜伏期较长(20-25毫秒)的反应占优势。发现VM和DL对两类皮质神经元均有影响,一类对躯体感觉刺激(单、双和多价)敏感,另一类对肢体的皮肤电刺激无反应。
