Human sensory nerve compound action potential amplitude: variation with sex and finger circumference
Abstract:
The amplitude of human, antidromic, sensory compound action potentials (CAP) recorded from median and ulnar digital nerves is greater in females than males. This sex difference is probably due entirely to females having digits of smaller circumference, resulting in digital nerves being closer to the recording ring electrode enclosing the digit. The negative linear correlation between CAP amplitude and circumference holds true for persons of the same sex.
