Resetting of cortically induced rhythmical jaw movements by stimulation of the cerebellar interpositus nucleus in the guinea pig.
Effects of stimulation of the cerebellar interpositus nucleus on fictive rhythmical jaw movements induced by stimulation of the cortical masticatory area were studied in ketamine-anesthetized, paralyzed guinea pigs. A short pulse-train applied to the interpositus nucleus caused a phase shift in cortically induced rhythmical jaw movements. A phase transition curve indicated that interpositus stimulation can reset the cortically induced rhythmical jaw movements.
