Monoamine oxidase-containing neurons in the cat hypothalamus: distribution and ascending projection to the cerebral cortex.
Using a recently developed monoamine oxidase (MAO) histochemical technique, we show the existence of MAO-containing neurons in the cat hypothalamus. In conjunction with retrograde tracer technique with horseradish peroxidase, we further demonstrate that virtually all posterior hypothalamic neurons projecting directly to the occipital cortex contain MAO, an amine catabolizing enzyme.
