Description
Summary:	The neuronal impulse reactions of the motor cortex neurons (field 4) which are involved in the reflex realization were studied on the awakening cats trained to perform conditioned movement after the influence of two stimuli (the preliminary and the conditional). Slow cortex potential in vertex was registered simultaneously. It was established that before the response to the triggering signal (interstimuli period) high amplitude negative shift in the slow cortex potential is present. At the same time we registered inhibition of neuron activity which led to excitative reactions represented as potent impulses. The obtained results allow us to suggest a relationship between the development of negativeness and inhibition of motor cortex neurons during preparation to the movement.
