This higher-power view of the ventral mesencephalon at age E 90 illustrates the dense packing of DA neurons as well as the highly developed dendritic bundles (arrows) that course from the substantia nigra zona compacta (ZC) into the zona reticulata (ZR). Ascending axons en route to the striatum are seen in the upper left corner of this photograph.
