On- and off-responses to a prolonged optical stimulus (up to 1000 ms) were studied in the cat sensomotor cortex. Similarity of the minimum time of stimulation resulting in the off-response with the cycle of the functional restoration after a single flash was observed. It is suggested that IPSP arising in the cortical neurons form a basis of these time intervals. The influence of stimuli of other modalities (cutaneous) on the off-responses is shown. This influence was observed in the case when the cortical neuron produced an impulse discharge to the cutaneous stimulus.
