1. Dopamine applied iontophoretically to neurones of the caudate nucleus of cats caused excitation of some (9% of those encountered) and depression of others (60%). Some cells have been found affected both by dopamine and by acetylcholine.2. The effects of dopamine could be prevented by the previous iontophoretic administration of phenoxybenzamine, but not by dichloroisopropylnoradrenaline.3. Responses evoked in caudate neurones by electrical stimulation of substantia nigra were depressed by… CONTINUE READING
