[Responses of neurons of the associative parietal cortex during acute extinction restoration of a conditioned reflex].

The dynamics of spike neuronal activity in the parietal associative cortex was studied in the course of acute extinction and restoration of a conditioned reflex. Certain similarities have been found in neuronal firing during the reorganization of behavioral acts (transient processes in neuronal activity, general types of neuronal responses, etc.) The data obtained suggest the involvement of neurones of the parietal associative cortex in the processes related to the reorganization of behavioral acts, and the existence of common mechanisms of search for an optimal regime of neuronal assemblies functioning in different types of conditioned activity.
