A, Pie-chart showing the proportion of canonical-mirror (left) and canonical (right) neurons with visual presentation responses selective or unselective for a specific orientation of the presented object. B, Correlation between the visual responses triggered by object presented with 0° and 90° orientation in canonical-mirror and canonical neurons. C, Comparison among object presentation responses during the fixation (OTe-fix) and grasping (OTe-grasp) conditions of the OTe, the OTp, and the fixation (VMT-fix) and grasping (VMT-grasp) conditions of the VMT. *p < 0.001. ns, not significant.
