Computer-generated 3-D reconstruction from case R120, after injection of BDA into the trunk representation of SI. The labeling in the right pontine nuclei consists of two to three clusters. A small rostral cluster and a larger caudal cluster are shifted towards lateral. From the dense, caudally located cluster, a bandlike zone of sparse labeling extends towards the midline. The sparse contralateral labeling is not shown. Bar = 500 µm.
