Computer-generated 3-D reconstruction from case R113,
after injection of BDA into the upper lip representation of SI. The labeling
is located centrally in the right pontine nuclei and consists of a large laterally
located cluster and a smaller medially located cluster. The clusters are connected
through thin rostral and caudal bridges of fibers that surround a zone devoid
of labeling. The sparse contralateral labeling is not shown. Bar = 500 µm.
