Electrode implantation sites in the RAIC, ACC, and S1. For each brain area, the represented photomicrographs of the histological section are shown in the upper panels. The recording sites were determined by electrolytic lesions at the end of the microwire tracks (arrowheads). The summaries of all recording sites for the unit recordings are shown in the lower panels. The electrode target on the contralateral side is labeled with triangular symbols (▲) and those on the ipsilateral (left) side of the RAIC is labeled with circles (●). Each color represents an electrode site for one individual. Numeral unit for the anterior–posterior length from the bregma (AP) is in millimeters
