Electrophysiological evidence of the connections between the globus pallidus and other divisions of the central nervous system in man

Introduction of a needle-electrode into the pallidum during hemipalidectomy usually arrested the theta-rhythm recording from the cortex of the ipsilateral hemispheres, in parallel with a temporary reduction or disappearance of the tremor on the contralateral upper extremity. These data point to a more rapid appearance of descending pallidum influences (on the motor spinal cord centers) than of the ascending ones (on the cortex of large hemispheres). Introduction of the needle also caused disturbances of the vegetative functions (respiratory, cardiovascular, and others). In cases of significant vegetative functional disturbances there was generalized high-amplitude theta-rhythm recorded on the electroencephalograms and electropallidograms.
