In this study we have demonstrated an enhancement of cortically generated wave forms of the somatosensory evoked potential (SEP) following magnetic pulse stimulation of the human brain. Subcortically generated activity was unaltered. The enhancement of SEP amplitude was greatest when the median nerve was stimulated 30-70 msec following magnetic pulse stimulation over the contralateral parietal scalp. We posit that the enhancement of the SEP is the result of synchronization of pyramidal cells in the sensorimotor cortex resulting from the magnetic pulse.
在本研究中，我们证明了对人脑进行磁脉冲刺激后，体感诱发电位（SEP）的皮层产生波形增强。皮层下产生的活动未改变。当在对侧顶叶头皮进行磁脉冲刺激后30 - 70毫秒刺激正中神经时，SEP幅度的增强最大。我们推测SEP的增强是磁脉冲导致感觉运动皮层中锥体细胞同步化的结果。
