Poststimulatory inhibition of galvanic skin reflex in anesthetized cats

¹ Laboratory of Neurophysiology, University of Wisconsin, Madison, Wisconsin

A galvanic skin reflex is elicited in an anesthetized cat by stimulation of one sensory or mixed nerve and, 10 seconds later, another galvanic skin reflex is elicited by stimulation of a second sensory or mixed nerve with current of the same parameters. The amplitude of the second reflex is reduced just as it is by restimulation of the first nerve at the same interval. This fact indicates that the decrease in amplitude of the second reflex is not due to the fatigue or subnormality of the afferent branch of the arc of the galvanic skin reflex.
