title: Demonstration of monoamine oxidase type B in serotonergic and type A in noradrenergic neurons in the cat dorsal pontine tegmentum by an improved histochemical technique.
abstract: Application of a diaminobenzidine-coupled peroxidation method to monoamine oxidase (MAO) histochemistry demonstrates a detailed morphology of MAO-containing perikarya, dendrites, axons and fibers in the dorsal pontine tegmentum of the cat, sectioned with a vibratome. Further, utilization of specific inhibitors, deprenyl and clorgyline, also provides evidence that serotonergic neurons contain exclusively MAO-B and catecholaminergic ones contain MAO-A.
