Effects of intraventricular and intra-aquaductal 6-hydroxydopamine on monoamine containing neurons of the fowl paleostriatum, diencephalon and mesencephalon.

The effects of a single intraventricular or intra-aquaductal infusion of 6-hydroxydopamine (6-OHDA) on monoamine fluorescence in the paleostriatum augmentatum, diencephalon and mesencephalon were studied. Present experiments have enable us to better characterize the distribution of catecholaminegic axons in the paleostriatum augmentatum, preoptic area, hypothalamus, median eminence, periventricular areas as well as of cell-bodies and axons exbiting green fluorescence in the n. mesencephalicus properties and other mesencephalic nuclei.
