Figures & data

Figure 1 Rats of MCAO model were treated with EA at the “Baihui” acupoint and “Dazhui” acupoint.

Notes: (A) Rats under EA treatment. (B) The front needle position is at the “Baihui” acupoint, and the other is at the “Dazhui” acupoint.
Abbreviations: MCAO, middle cerebral artery occlusion; EA, electroacupuncture.
