[Comparative analysis of the latent periods of adjacent neurons in microareas of the visual cortex].
Latencies of responses to heteromodal stimuli were determined for neurones of the cat visual cortex recorded with different amplitudes of action potentials (AP). Latencies of responses of three neighbouring neurones recorded with one microelectrode were compared. It was shown that in the case of light stimulation, the neurone recorded with a smaller AP amplitude, as a rule entered the reaction before the neurone recorded with a greater AP amplitude; in response to acoustic stimulation, the reverse relationship was observed. In most of the microareas in which response latencies of the neighbouring cells differed slightly, crosscorrelograms revealed action of "the common input". Comparative analysis has shown that an afferent wave excites each of the microarea cells separately.
