Note. (for CV4, n = 20, for CV12, n = 18, P < 0.05/T > 1.3) True RS (resting state): The resting state session before sham EA.

MPF: medial prefrontal cortex, Orbital F: orbital frontal cortex, Ventra ACC: ventral anterior cingulate cortex, FP: frontal pole, HP: hippocampus, ParaHP: parahippocampus, TP: temporal pole, SN: substantial nigra, PCC: posterior cingulate cortex, LMF: lateral middle frontal cortex, and PAG: periaqueductal gray matter.

The brain regions showing enhanced post-EA local connectivity were similar for two acupoints: medial prefrontal cortex BA10/11, anteroinferior portion of the anterior cingulate cortex BA24/32, BA25, followed by hippocampus, parahippocampus. Differences were seen in Amygdala and Marginal gyrus, BA40 (CV4 > CV12).
