[Role of emotional excitation in mechanisms of spatial short-term memory in lower monkeys].

: Correlates of the changes of emotional tension level were studied in adult macaca rhesus. Simultaneous appearance of skin-galvanic responses and changes of heart rate were shown to reflect the increase of emotional tension level. The latter was revealed with continuous recording of the above vegetative indices during presentation of conditioned signals and performance of spatial delayed response. Emotiogenic structures are supposed to have a promoting effect on functioning of the mechanisms of spatial short-term memory during the period of spatial discrimination of conditioned signals and food-procuring instrumental behaviour.
