[The neuronal activity of the caudate nucleus in monkeys during the realization of delayed behavior].
A greater part (64%) of recorded neurones of the caudate nucleus head changed its activity at various stages of fulfillment by the monkey of the task of delayed spatial choice. Most of them (46.5% of all studied) reacted at key depressing and/or taking food from the feeder. During signal presentation and with delay the frequency of impulse activity changed respectively in 17% and 14% of the studied neurones. Besides, 2 neurones had spatially-selective activity in the instructive period of the program. It can be suggested that caudate neurones participate in realization of the delayed behaviour not only during motor response fulfillment but in the instructive period as well--at the stage of perception and processing of the visual information and its storing in short-term memory.
