Figure 3.

Cytochrome oxidase demonstration of the location of the MPt and TLC. The location of nuclear borders on the right is demonstrated with respect to cytochrome oxidase staining on the left. The MPt can be found lateral to the dorsomedial surface of the midbrain (A, B). This same region contains the TLC at more caudal levels (C–F). The possible borders of the ventral TLC are indicated by the dotted lines. We placed the caudal border of the MPt at the rostral border of the superior colliculus. Scale in F = A–E.
