Abstract

Neuronal responses of the dorsomedial thalamic nucleus of anesthetized rats to stimulation of the anterior periamygdalar cortex were compared before and after destruction of the basolateral nuclei of the ipsilateral amygdala. After destruction of the afferent inflow from the nuclei of the amygdala a new type of response appeared, in the form of prolonged generation of bursts of spikes, and also a significant decrease in the number of cells with a phasic activation response and an increase in the number of tonically activated neurons. Destruction of the amygdala was shown to lead to an increase in the number of cells of the dorsomedial nucleus with spontaneous activity. The duration of the tonic spike response in animals undergoing the operation was found to be significantly increased from 142.5±42.4 to 375.4±53.8 msec, whereas the parameters of other types of neuronal responses did not differ statistically significantly.
