title: [Analysis of the participation of rat brain noradrenergic terminals in elaboration of conditioned passive avoidance response].
abstract: A change in a noradrenaline concentration in the noradrenergic terminals was investigated by the fluorescent histochemical method in pars ventralis nuc. interstitialis striae terminalis, nuc. septi lateralis and in nuc. preopticus medialis of male Wistar rats in the process of reproduction of conditioned passive avoidance response. In all the investigated structures of the preliminarily trained animals the reproduction of a conditioned response (without any electrical stimulation) led to a statistically reliable decrease in the noradrenaline concentration. The data obtained testified to the participation of the noradrenergic brain system in the reproductive process of the conditioned passive avoidance response.
