the effects of morphine and aoaa on the turnover of brain catecholamines ( ca ) were determined by measuring both the accumulation of dopa after inhibition of central aromatic l-amino acid decarboxylase and by measuring the depletion of noradrenaline ( na ) after inhibition of tyrosine hydroxylase by alpha-methyltyrosine ( alpha-mt ) .
