  • Title: [Transcallosal modulation of a focus of maximal activity in the motor cortex].
    Author: Bianki VL, Makarova IA.
    Journal: Fiziol Zh SSSR Im I M Sechenova; 1977 Oct; 63(10):1376-83. PubMed ID: 923844.
    Abstract:
    In acute experiments on cats, when recording EPs from 170 symmetrical points of the motor cortex, callosal influence on the maximal activity focus (MAF) was studied in conditions of stimulation of the sciatic nerves with different stimuli. After callosal transection, weak stimuli enlarged the MAF, strong one-narrowed it. The transcallosal modulation in intact brain is supposed to aid to delineate the MAF in the motor cortex and to exaggerate the differences between MAFs occurring at stimulation with different stimuli.
