Abstract

Somatosensory cortex (SI) activity was enhanced using anodal transcranial direct current stimulation (tDCS) in 59 participants (ages 19–36) while rating emotional responses to images of humans or objects either touching or not. Individuals with low affective empathy show reduced emotional ratings to positive social interaction during tDCS to SI.
