Functional magnetic resonance imaging connectivity analyses reveal efference-copy to primary somatosensory area, BA2.

Some theories of motor control suggest efference-copies of motor commands reach somatosensory cortices. Here we used functional magnetic resonance imaging to test these models. We varied the amount of efference-copy signal by making participants squeeze a soft material either actively or passively....
