    Abstract:
    Influence of microinjections of monoamines and glutamic acid into the caudate nucleus head on conditioned food-procuring reaction was studied in experiments on rats. Dopamine, noradrenaline and glutamic acid prolong the latency of the reflex, while serotonin reduces it. However, all the drugs tested reduce the number of conditioned food-procuring movements. The effects of dopamine are achieved through neurone receptors of the caudate nucleus which are sensitive to haloperidol and chlorpromazine; effects of serotonin are mediated through the D-serotoninoreactive systems, and those of noradrenaline, through the alpha-adrenoreactive systems of the neostriatum neurones. The inhibitory effect of glutamic acid is not due to the action on the serotonino-, adreno-, or dopamine receptors of caudate units.
