The right hemisphere dominates in face-related self-recognition processes. Here, by using TMS over the left and right motor cortex we show that vision of one’s own hand (and cell-phone) increases corticospinal excitability selectively for the right hemisphere, and at relatively late timings. Our findings suggest that owned hands and objects may undergo similar self-processing, although possibly via a different cortical network from that responsible for self-face processing.
