A depressant area in the lateral nodulus-uvula of the cerebellum for renal sympathetic nerve activity and systemic blood pressure in the rabbit.
Electric stimulation at the nodulus and uvula of the cerebellum with a train of 5-10 pulses caused a marked depression of the renal sympathetic nerve activity. The effective sites were located in a small lateral region extending through the dorsal nodulus and encroaching the ventral uvula, at 2.9-3.7 mm lateral to the midline. The depression occurred predominantly contralaterally. Stimulation at this region with pulse trains lasting for several seconds caused a transient reduction of systemic blood pressure.
