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.
从中指和尺指神经记录到的人类逆向感觉复合动作电位(CAP)的幅度在女性中比男性更大。这种性别差异可能完全是由于女性手指周长较小,导致指神经更靠近围绕手指的记录环电极。CAP幅度与周长之间的负线性相关性在同性别的人群中成立。
