Application of heteromodal extrastimuli (ES) promotes selected excitation of most of the responding neurons in the thalamic reticular nucleus (R). Twelve of 32 tested neurons responded to visual ES and 4 from 21 tested neurons responded to auditory ES. Initial responses of neurons and quantity of cells with initial responses decreased during habituation to ES. Grouped discharges disappeared after external stimulation. Initial responses to ES and to the following conditional stimulus appeared during external inhibition (EI), while late responses usually accompanying conditioning were inhibited almost in half of the studied neurons. It was suggested that R neurons participated in EI and in habituation to ES.
应用异模态额外刺激(ES)可促进丘脑网状核(R)中大多数反应神经元的选择性兴奋。在32个受试神经元中,有12个对视觉ES有反应,在21个受试神经元中有4个对听觉ES有反应。在对ES产生习惯化的过程中,神经元的初始反应以及有初始反应的细胞数量均减少。外部刺激后成组放电消失。在外部抑制(EI)期间出现对ES和随后条件刺激的初始反应,而通常伴随条件作用的晚期反应在几乎一半的研究神经元中受到抑制。有人提出,R神经元参与了EI以及对ES的习惯化过程。
