ABSTRACT

Sympathetic skin nerve action potentials were recorded in the median nerve of 5 healthy college students. A linear and significant correlation was found between the mean voltage amplitude of the sympathetic bursts and the amplitude of skin resistance responses (SRRs). Thus amplitude of skin resistance responses seems to be an index of sympathetic activity.
