Description

Neuromelanin formation in the dopaminergic neurons of the substantia nigra exhibit various developmental phases. The proportion of the cell occupied by the pigment remains constant in adults. However both biochemical measurements of solublized neuromelanin and direct counts of isolated pigment granule numbers using flow cytometry indicate that the amount of pigment progressively increases with advanced age.
