Computer-generated 3-D reconstruction from case R117,
after injection of BDA into the forelimb representation of SI. The labeling
in the right pontine nuclei consists of two to three clusters surrounding a
centrally located non-labeled zone (which contains projections from perioral
representations, cf. R103, R105, R106, R113), with a small centrally located
rostral cluster and larger caudal clusters that merge into a widespread band
extending in the mediolateral dimension. The sparse contralateral labeling is
not shown. Bar = 500 µm.
