经颅电刺激可引发相对同步的肌肉反应,即运动诱发电位,运动诱发电位反应的潜伏期与快传播性皮质脊髓束的激活一致,这种方法可应用于很多方面,但存在可能同时诱发疼痛的问题。而经颅磁刺激可刺激神经和大脑,且几乎没有疼痛,已被广泛应用于研究人体大脑的生理学诸方面,包括运动功能和各种大脑疾患的病理生理。 Transcranial electrical stimulation can trigger a relatively synchronous muscle response, that is, motor evoked potentials. The latency of motor evoked potentials is consistent with the activation of rapidly transcortical corticospinal tracts. This approach can be applied in many ways but with the potential for concurrent pain-inducing problem. Transcranial magnetic stimulation can stimulate the nerves and brain, and almost no pain, has been widely used in the study of human brain physiology, including motor function and pathophysiology of various brain disorders.
