Reversal of beta-amyloid-induced retention deficit after exposure to training and state cues.


We explored amnesia induced by posttraining injection of beta-amyloid protein (beta A4) in four experiments. Previous reports showed that beta A4 impaired retention of learning maintained either by food reward or by shock relief. The experiments in this paper attempted to determine (1) if the amnesia is specific to the 1-40 beta A4 amino-acid sequence; and… (More)
