Abstract

Spike responses of 104 neurons of the nucleus reticularis thalami (R) and neighbouring thalamic nuclei to the acoustic stimuli, tactile and visual stimulation were studied in the chronic experiment. 29% of neurons responded to the acoustic stimulation and 11% of them were not specific to different acoustic stimuli. The minimal latency of the excitation to the acoustic stimulation was 12-37 ms and that of the inhibition--18-27 ms. The duration of the excitation in response to the acoustic stimulation was 50-250 ms and that of inhibition--27-190 ms. 16% of R neurons responded to the stimulation of different sensory systems. The majority of R neurons showed excitation in response to different stimuli and only 4-10% of neurons showed inhibition.

摘要

在慢性实验中,研究了丘脑网状核(R)及邻近丘脑核的104个神经元对听觉刺激、触觉和视觉刺激的锋电位反应。29%的神经元对听觉刺激有反应,其中11%对不同的听觉刺激无特异性。对听觉刺激兴奋的最小潜伏期为12 - 37毫秒,抑制的最小潜伏期为18 - 27毫秒。对听觉刺激反应的兴奋持续时间为50 - 250毫秒,抑制的持续时间为27 - 190毫秒。16%的R神经元对不同感觉系统的刺激有反应。大多数R神经元对不同刺激表现为兴奋,只有4 - 10%的神经元表现为抑制。
