Biogenic amine terminals in the goldfish cerebellum and optic tectum: a fluorescence and autoradiographic study

The intraventricular administration of 3H-noradrenaline was used to demonstrate the presence and the distribution of the monoaminergic terminals in the goldfish cerebellum and optic tectum. Monoaminergic terminal can be selectively labelled by tritiated neurotransmitter and are visualized by light and electron microscopic autoradiography. Further evidence of the presence of catecholamines in these encephalic areas was furnished by the induced-fluorescence technique.
