Figure 5.
A: Some axons (arrows) of the ventral mesencephalon at E 55 appear to course through the internal capsule (IC) as they ascend through the putamen (PT) and caudate nucleus (CD). B: Components of the ascending monoaminergic systems are seen as they pass through the region of the medial forebrain bundle at a diencephalic level. Although identifiable, the fiber density is minimal in comparison to stage E 90 as illustrated in Fig. 6.
