title: [Effect of a decrease in brain noradrenaline and serotonin levels on defensive and food-getting conditioned reflexes in rats].
abstract: The influence of pharmacological and surgical interferences in the activity of serotoninergic and catecholaminergic brain systems on elaboration and consolidation of conditioned reflexes was studied in rats. Ablation of the locus coeruleus, nucleus raphe and administration of inhibitors of monoamines synthesis reduced noradrenaline and serotonin (5-OT) content in rat's brain. Ablation of the locus coeruleus and disulphiram administration impaired mainly the elaboration of defensive and alimentary conditioned reflexes. Ablation of the nucleus raphe and parachlorphenilalanin administration affected predominantly the retention of the reflexes. At the same time, the effects of surgical and pharmacological interferences differed in some respects
