A, Locations of all the receptive fields on the face for monkey MCh21 that were observed in the normal face region lateral to the hand–face border. This region is marked as region A′ in the inset shown at the bottom (see Fig. 12 A). The receptive fields are located all over the face as in a normal monkey. B, Locations of all the receptive fields on the face that were found in the reorganized cortex medial to the hand–face border and lateral to the trunk representation marked as region B′ inset shown at the bottom. Note that the receptive fields at all the recording sites are confined to the chin except for one receptive field that extends to the upper lip. C, Locations of all the receptive fields on the face that were found in the reorganized cortex medial to the trunk representation marked as region C′ inset shown at the bottom. The receptive fields at all the recording sites were confined to the chin as for the region B′.
