[Functional and biochemical reorganization in hyperfunction of the dopaminergic system]. / Funktsional'nye i biokhimicheskie perestroiki v usloviiakh giperfunkttsii dofaminergicheskoi sistemy.

In dogs, cats, rabbits, the effects of unique and chronic administration of L-DOPA (20-50 mg/kg daily) on central dopamine processes, behaviour, interrelations of sensory and motor regimens of the structures and on the transmitter metabolism, were studied. The interrelations of sensory and motor regimens became competitive, reciprocal changes occurred in dopaminergic and other transmitter (serotoninergic and acetylcholinergic) systems. The findings seem to be related to development of psychomotor excitation.
