The functional bases for the formation of sensory system interaction in ontogeny

The study of the mechanisms of the intersensory interaction and its development in the postnatal ontogenesis. The first proved evidence of participation of the intracortical inhibition mechanisms in the processes of heterosensory interaction on the cortical level. The study of formation in kittens of the heterosensory interaction on the neurons of the sensorimotor cortex area has established the correlation of the process with the interconnected maturing of the afferent entries to this cortex area, and the system of intracortical inhibition. Correlation was established between the time of development of the heterosensory interactions on neurons of the sensorimotor cortex area in ontogenesis and the age period when injury of the sensorimotor cortex destroys the ability of animals to produce a conditioned reflex to a complex heteromodal signal in case of inhibiting reactions to its components. Discussion of the problem of input of the cortical level to the process of heterosensory interaction in different phases of ontogenesis.
