The effect of syrosingopine on retention of a passive avoidance trial in mice was investigated. The drug given in doses of 2.5, 4.0 or 6.0 mg/kg 2 hr before training, but not when given 24 or 0.5 hr before or immediately after training, resulted in amnesia 7 days later. Dopamine or norepinephrine administered systemically 15 min before to 10 min after training was able to block the syrosingopine-induced amnesia. The role of peripheral catecholamines in memory formation was discussed.
