(a) Anatomical image of the rat skull seen from above. The asterisk indicates the bregma, and the circle marks the lambda. (b) Intraoperative image: skull thinning for a total diameter of 5Â mm was performed. The outer plate and diploe of the skull were removed, leaving only the inner plate. The anode was installed on the lambda, and the cathode was installed on the bregma. (c) The electrode installation. Transcranial electrical stimulated motor-evoked potentials were recorded under general anesthesia.
