Role of inhibition in the formation of a dynamic mosaic of neuronal ensembles in the cerebral cortex.

The spatial-temporal organization of neuronal responses in the rat visual cortex was investigated during the action on the retina of light stimuli of various size. It was shown that a leading role in the formation of a dynamic mosaic of neuronal ensembles belongs to inhibition. Two systems of inhibition are distinguished, involved in differing degree in the organization of the operating mechanisms of the brain during the action of various stimuli.
