The sympathetic skin responses (SSRs) were recorded from different facial regions and neck in 25 subjects evoked by electrical stimulation of the median nerve at the wrist. Recordings from all regions were cross-compared with each other and within right and left sides individually. In one subject postauricular SSR, and in another subject upper lip SSR could not be elicited on both sides. Other responses could be obtained in all the remaining subjects. In 11 subjects, the responses did not appear by the first stimulus, and began to appear by repeated stimuli. Mean latencies and the highest amplitudes of the responses were similar for both sides. Gradual amplitude increase was observed in the first three or four set of responses in 20 subjects, although the stimulus intensity was constant. In conclusion, face and neck SSRs are symmetric, can be evoked by electrical stimulation and can be used to investigate the sympathetic innervation of these areas.
对25名受试者通过电刺激腕部正中神经，记录不同面部区域和颈部的交感神经皮肤反应（SSR）。所有区域的记录相互之间以及左右两侧分别进行交叉比较。在一名受试者中，双侧耳后SSR未引出，在另一名受试者中，双侧上唇SSR未引出。其余所有受试者均可获得其他反应。在11名受试者中，首次刺激时未出现反应，重复刺激时开始出现反应。两侧反应的平均潜伏期和最高振幅相似。在20名受试者中，尽管刺激强度恒定，但在前三四组反应中观察到振幅逐渐增加。总之，面部和颈部的SSR是对称的，可通过电刺激诱发，可用于研究这些区域的交感神经支配。
