Monoamine distribution in primate brain. I. Catecholamine‐containing perikarya in the brain stem of Macaca speciosa

Abstract

The distribution of catecholamine‐containing cell bodies was examined in the brain of Macaca speciosa using the Falck‐Hillarp histofluorescence technique. Extensive accumulations of such cells were seen in the ventral tegmental area, locus coeruleus, mesencephalic reticular formation and ventrolateral reticular formation of pons and medulla. This distribution was compared to that previously reported in rat, cat, squirrel monkey and human brain. Apparent species dissimilarities and similarities are reported.
