Computer-generated 3-D reconstruction from case R102, after twenty injections of BDA throughout SI. A large non-uniform area of labeling is located centrally, dorsally and caudally in the right pontine nuclei. A zone with low labeling density is situated medial to the intersection of the dotted reference lines (ventral view, sagittal slices 20 - 40, transverse slices 30 - 60). The sparse contralateral labeling is not shown. Bar = 500 µm.
