  • Title: Motor cortex activation induced by a mirror: evidence from lateralized readiness potentials.
    Author: Touzalin-Chretien P, Dufour A.
    Journal: J Neurophysiol; 2008 Jul; 100(1):19-23. PubMed ID: 18480370.
    Abstract:
    Similar motor regions are activated during voluntarily executed or observed movements. We investigated whether observing movements of one's own hand through a mirror will generate activations in the cortical motor regions of both the moving and nonmoving hands. Using the lateralized readiness potential (LRP), an electrophysiological correlate of premotor activation in the primary motor cortex, we recorded evoked responses to movements while subjects were viewing the performing (right) hand through a mirror placed sagittally, giving the impression that the left hand was performing the task. Reliable LRPs were recorded in relation to the seen hand, indicating motor cortex activity in the contralateral hemisphere of the inactive hand while the opposite hand was performing the movement.
