  • Title: [Interzonal transcallosal connections of the sensomotor cortex].
    Author: Bianki VL, Shramm VA, Kharitonov EV.
    Journal: Fiziol Zh SSSR Im I M Sechenova; 1989 Apr; 75(4):433-40. PubMed ID: 2759278.
    Abstract:
    Interzonal transcallosal EPs occurring in response to stimulation of visual or auditory cortex of opposite hemisphere, were recorded in the cat sensomotor cortex. Visual-motor EPs had mainly an initial positivity whereas audio-motor those were mainly initially negative. Latencies of the former EPs were longer. Negative--positive visual-motor EPs had a greater amplitude than their synphasic audio-motor ones. Initially positive EPs had a greater amplitude in stimulation of A1 rather than 19. The EPs revealed an interhemisphere asymmetry: audio-motor those were greater in the left hemisphere mainly in females. The specifics of the asymmetry seems to be due to an interzonal asymmetry of transcallosal flows of projectional and associative cortical areas.
