[Facilitation of memory trace retrieval by the action of amfonelic acid].

Amfonelic acid exerting the central dopaminergic effect was studied on mice by the passive avoidance conditioned response method under amnesia induced by leaving the animals in a dark chamber following electrocutaneous stimulation and different terms of natural forgetting. Amfonelic acid was shown to prevent the amnesic effect, to improve retrieval of the conditioned response decreased as a result of amnesia or prolonged forgetting.
