[Bioelectrochemical activity of the cerebral cortex in the rabbit during voluntary movement].
In chronic experiments on rabbits, BEchA was studied on platinum and silver electrodes implanted up to the brain surface. Platinum electrodes exhibited greater than the silver ones sensitivity to metabolites discharged to the surface of the brain during preparation for and performance of motor reactions. BEchA studies on platinum electrodes have revealed nonuniformity of motor reactions. In some cases the systems which organize them, involve metabolic processes, in others the outwardly similar movements develop without the participation of such systems and are not attended with BEahC changes. Two factors accounting for regular BEchA changes have been established: the animal's state of "alarm" and a locally changed metabolism in the sensorimotor area.
