| The brainstem and basal forebrain are illustrated at E 55 following staining for tyrosine hydroxylase; rostral is to the left. In A, it is apparent that the ventral mesencephalon is filled with DA neurons (arrows) that have completed their migration from the germinal epithelium. In B, they appear densely packed and have minimal neuritic arborization at this level. |
