[Monoaminergic mechanisms of the amygdaloid complex actualizing conditioned reflexes of different biological modality].

Microinjection of dopamine and serotonin into the dorso-medial portions of the amygdalic complex of rats increased the latent period of conditioned defense and motor food reactions, spontaneous motor activity, the number of jerks and the value of the conditioned food reflex. Noradrenaline failed to influence the recorded indices of the conditioned food-procuring reflex, but facilitated the conditioned reaction of avoidance, significantly shortening its latent time. The results obtained pointed to the specificity of the neurochemical mechanisms realizing at the level of the amygdalic complex conditioned reflexes of various biological modality in rats.
