title: Catecholamine levels in the whole brain and the probability of memory formation are not related.
abstract: Amnesia was induced with reserpine or was blocked with 1-dopa and 5-hydroxytrptophan before or after passive avoidance training in mice. The levels of dopamine and norepinephrine in the whole brain were measured in corresponding groups with gas chromatography-mass spectrometry. No correlation was found between retention and the levels of these catecholamines in the brain.
