The Instant Effects of Continuous Transcutaneous Auricular Vagus Nerve Stimulation at Acupoints on the Functional Connectivity of Amygdala in Migraine without Aura: A Preliminary Study

Figure 6

The functional connectivity (FC) of the right amygdala in MwoA during continuous stimulation (taVNS vs. staVNS). SAG: sagittal; COR: coronal; TRA: transverse; FWE: familywise error correction. Compared with staVNS, the FC of the right amygdala and left frontal middle gyrus significantly decreased during taVNS (voxel-level and cluster-level ).
