Skin potential and EMG responses induced in normal man by electrical stimuli applied to the skin were recorded in the four limbs in order to study somato-sympathetic and somato-motor reflexes. Different patterns of responses were observed in different conditions: alarm, habituation, sensitization and arousal. During alarm, sensitization and arousal, the responses were present in the four limbs; during habituation, the responses were only present in the stimulated and in the contralateral limb. Three sensory thresholds to cutaneous electrical stimulation were identified in habituated subjects: tactile, tingling and pain. Cutaneous and EMG responses appeared at tingling threshold. A relationship between skin potential level and skin potential response was observed.
为了研究躯体交感和躯体运动反射，对正常人四肢施加电刺激诱导的皮肤电位和肌电图反应进行了记录。在不同条件下观察到不同的反应模式：警觉、习惯化、敏感化和觉醒。在警觉、敏感化和觉醒期间，四肢均有反应；在习惯化期间，反应仅出现在受刺激的肢体和对侧肢体。在习惯化的受试者中确定了三种皮肤电刺激的感觉阈值：触觉、刺痛和疼痛。皮肤和肌电图反应出现在刺痛阈值。观察到皮肤电位水平与皮肤电位反应之间的关系。
