[Inhibition of neuronal responses in the cat motor cortex, associated with attainment of a conditioned reflex when waiting for a flash of light].

Inhibition of neuronal spike reactions associated with reflex movements and induced by the light flare at different moments during the conditioned stimulation (1 s.) has been found in chronic experiments on cats. The light flare in the interval of maximum probability of the reflex realization has promoted a rise in the neuronal latency by 300-400 ms and a decrease of their duration almost twice. Other realizations of the inhibition effect were weaker.
