Phenomena of the Hypokinetic Rigid Type caused by O-methylation of Dopamine in the Para-position

Abstract

THE investigations of Carlsson1,2, by which he demonstrated that practically all dopamine in the mammalian brain is found in the caudate- and entiform-nucleus (forming an important part of the extrapyramidal system), whereas norepinephrine is present in only minimum quantities, suggest that the function of dopamine is not merely that of a precursor of norepinephrine. Carlsson showed, moreover, that reserpine depletes the dopamine from the corpus striatum and produces a Parkinsonian syndrome which could be counteracted by dopa, the precursor of dopamine.
