Dopamine: Release from the Brain in vivo by Amantadine

Abstract
After dopamine stores in the caudate nucleus of cats were labeled with [3H]dopamine, the ventricular system was perfused with artificial cerebrospinal fluid. The addition of amantadine to the perfusing fluid caused a doserelated increase in the concentrations of [3H]dopamine appearing in the perfusion effluent. Subthreshold concentrations of amantadine also enhanced the efflux of [3H]dopamine induced by electrical stimulation of the caudate nucleus.
