• To explore the excitatory effect of the sensory cortex through somatic electroacupuncture (EA) stimulation at Taichong (LR3). Ten healthy volunteer men ranging in age from 20 to 50 years were enrolled in this study. EA (2 Hz, a tolerable strength) was applied to the left LR3. Before and after EA, the somatosensory evoked potential (SEP) from the Cz' area of the scalp was recorded by electrical stimulation of the bilateral dorsal penile nerves and the indentation behind the medial malleolus of the foot, termed as the pudendal SEP (PSEP) and lower extremity SEP (LSEP), respectively. The amplitude of the left LSEP induced by stimulation of the left medial malleolus was significantly increased after EA (P < 0.05), but there were no significant changes in the latency of LSEP and PSEP, and the amplitude of right LSEP evoked by stimulation of the left medial malleolus, and that of the PSEP. EA at LR3 increases the excitability of the contralateral cerebral sensory cortex (lower extremity area), but has no effect on
