Abstract
Painful stimuli led to a decrease of the radioactive catecholamine pool in adrenalectomized rats. Intraventricular administration of both tritiated noradrenaline and ACTH produced a greater decrease of the labelled catecholamine pool than in the control adrenalectomized rats in 12 to 18 hr following injection. Blocking of monoamino-oxidase activity or biosynthesis by systemic administration of Pargyline or alpha-methyl-tyrosine did not prevent the effect of ACTH on brain catecholamines. It is concluded that ACTH exerts a direct influence on the brain catecholaminergic system and that this effect might be involved in ACTH dependent behavioural responses.
