Abstract Changes in the noradrenalin concentration in noradrenergic terminals were studied by a fluorescence-histochemical method in pars ventralis nuclei interstitialis striae terminalis, nucleus septi lateralis, and nucleus preopticus medialis in rats during passive-avoidance conditioning. In preliminarily trained animals the simple reproduction of the conditioned-reflex response (without electrical stimulation of the skin) led to a decrease in the noradrenalin concentration in all structures studied. The results indicate a role in the noradrenergic system of the brain in the reproduction of the passive-avoidance conditioned reflex.
