[Transcallosal modulation of functional interhemispheric asymmetry].
The course and mechanisms of individual functional interhemispheric asymmetry (FIA) were studied with the aid of evoked potentials (EP) in the visual, auditory, and motor cortex of cats. The FIA was revealed in majority of the animals. It was peculiar by its bilateral origin and mosaic character. A combined summation--reciprocal (dominant) type of interhemisphere interrelationships was shown to underlie the FIA. A spatial-strength transcallosal modulation of the FIA is supposed to exist.
