Transcranial direct current stimulation (tDCS) of the inferior frontal gyrus disrupts interpersonal motor resonance

► Frontal and parietal regions implicated in interpersonal motor resonance (IMR). ► Anodal and cathodal tDCS of frontal site impaired IMR. ► IMR not affected by tDCS of parietal site. ► Supports frontal but not parietal contributions to IMR.
