Electroacupuncture-Induced Plasticity between Different Representations in Human Motor Cortex

Figure 1

(a) Schematic drawings of a subject, showing the location of acupoint TE5 (Waiguan) and the target muscles. (b) Penfield and Rasmussen’s homunculus, in which representations of the leg, upper arm, forearm, hand, and face muscles are roughly arranged in a medial-to-lateral direction. (c) Experimental paradigm. All subjects participated in EA and sham EA groups. Abbreviations: COG: centre of gravity; DM: deltoid muscle; EA: electroacupuncture; EIP: extensor indicis proprius; FDI: first dorsal interosseous; OO: orbicularis oculi; TA: tibialis anterior; TE5: Waiguan acupoint.
