NEURAL MECHANISMS CONTROLLING THE PALMAR GALVANIC SKIN REFLEX AND PALMAR SWEATING

Abstract

Evidence that the autonomic nervous system as well as the innervation of the skeletal musculature finds representation within the cerebral cortex demands a revision of certain conceptions regarding the significance of autonomic changes. Especially is this the case with respect to the control of the palmar galvanic skin reflex and palmar sweat secretion.¹This peripheral autonomic activity, which available evidence indicates is related to manipulative activity, reactions of orientation and conative functions, may be linked neurologically as well as functionally through intermediate subcortical mechanisms, with activity at the higher cortical levels. The available evidence relating to the neural mechanisms is presented for consideration at this time, to the end that more attention may be given the phenomena in neurologic studies where applicable data are accessible, and that investigators having facilities may be led to help in the solution of the problems which are implied. Implications regarding the central mechanisms
