Effect of EA on cerebral infarct volume assessed by T2-Weighted MRI in Rats. a, b T2WI images of five brain slices of different levels (L10–L14 slices) from five different rats in each group before treatment and at Day 7 after EA. The ischemic lesion corresponds to the hyperintense region on each image. c The high intensity volume of T2WI calculated over all slices (infarct volume/volume of whole brains). Data are shown as mean ± S.E.M from 12 individual rats in each group. *P < 0.05, the MCAO/R + EA group versus the MCAO/R group; ## P < 0.01, the MCAO/R + EA group versus the MCAO/R+ Non-EA group
