Abstract
Impedance changes across the footpad of the cat occur as the result of sweat gland activity after stimulation of the sudomotor nerves. It is possible to discern two phases of impedance change; one, early, associated with the action potential of sweat gland cells; the other, later, being the well-known change associated with secretion and reabsorption.1 After a single stimulus, latency for the initial impedance change is about that of the sweat gland cell action potential, that of the secretory change approximately 1 additional second.
