Dance integrates bodily movement, rhythmic perception, and emotional expression, engaging complex sensorimotor and affective systems. However, its impact on the structural organization of empathy‐related brain networks remains insufficiently understood. In this study, we adopted a data‐driven approach to construct a structural empathy network based on neuroimaging data from 80 healthy university students and applied Granger causality analysis (GCA) to identify the directional impact of empathy on regional gray matter changes. Empathy ability was assessed using the interpersonal reactivity index (IRI) scale. To further examine training‐induced neuroplasticity, we employed an independent sample consisting of 25 dancers and 25 musicians, alongside 40 matched controls without formal artistic experience. Inter‐regional structural similarity, based on gray matter probability distributions, was calculated to capture modality‐specific plasticity due to dance/music training. Compared to musicians and controls, dancers exhibited significantly higher gray matter probability distributions, which indicates enhanced structural similarity between the left superior temporal gyrus and the left precuneus, left postcentral gyrus, and right paracentral lobule. Notably, this increased structural similarity was also associated with the empathy score ( r = −0.87, p < 0.05, family‐wise error FWE corrected). These findings suggest strengthened cross‐modal integration between perceptual and sensorimotor systems, potentially underpinning affective resonance. Our findings highlight the domain‐specific neuroplasticity of the structural empathy network induced by dance training and provide novel insights into how embodied practices shape socio‐emotional brain circuits.
