title: [Neuronal correlates of the functional reorganization of the dorsomedial thalamic nucleus in the rat after damage to the amygdala].
abstract: Activity of the thalamic dorso-medial nucleus (DMN) cells evoked by stimulation of the periamygdaloid cortex was recorded in anesthetized rats in various periods of time after the baso-lateral amygdala destruction. It was found that changes in functional characteristics of cells observed at the early postoperative period intensified and reached the highest expression 10-30 days after such a destruction. Both the number of responding cells and percentage rate of neurons with excitatory and inhibitory responses restored along with the prolongation of the postoperative period. The structure of evoked excitation differed from the normal in predominant long-lasting tonic activation. Some peculiar features of functional reorganization of the DMN neuronal network involved in processing of incoming afferentation are discussed.
