[Functional interhemispheric asymmetry in the motor cortex following stimulation of forelimb nerves]

It has been shown that in most animals electrical stimulation of the brachial plexus nerves results in a functional interhemispheric asymmetry in the motor cortex. It weakens after section of the callosal body. The asymmetry is characterized by a mosaic pattern. The data obtained are discussed as related to the role of dominant interhemispheric relations in contrasting the functional interhemispheric asymmetry and in the formation of a relatively homogeneous functional mosaic.
