[Nature of transcallosal responses in the parietal cortex of the kitten].
In immobilized 2-18 day old kittens, transcallocal responses in the parietal cortex involved a positive--negative complex often accompanied by a negative deviation. The early positive--negative oscillation had a callosal, and the late one--an extracallosal nature. The layer-to-layer analysis of the transcallocal responses showed that the source of positive-negative component, as kittens develop, was transferred from V to III layer, whereas the source of the surface negative component remained on the level of II-III layers. The late negative component, having the cource in the layer I-II, was registered only up to the II-IV layers. The interhemispheric relations in the parietal cortex of kittens are actualized both by means of callosal and extracallosal systems and, with age, their interaction is intensified.
