Computer-generated 3-D reconstruction from case D49, after injection of BDA and FR into SI whisker barrels located in different rows (A). The clusters of labeling are located within a single lamellar subspace (B: ventral view, C: slices 60 - 70, D: slice 70), and the black dots are located more dorsally than the red dots (B: transverse view, C: slices 60 - 90, D: slices 70 - 80). At certain locations where the pontine lamellar subspaces are sliced tangentially, the labeled clusters appear to display an inside - out shift. However, corresponding orthogonal slices reveal that the clusters also at these locations are located within a lamellar subspace (compare C: slices 40 - 50 with D: slices 60 - 70, see also B: ventral view).
