Large neocortical injuries can interfere with the initial performance of many previously learned behaviors. This dysfunction, however, may not be attributable to the loss of the memories of learned behaviors but to a failure to access memories that are spared. The results of this experiment support this hypothesis by demonstrating that the calcium entry blocker nimodipine, which prevents trauma-induced retrograde amnesia in a 1-trial passive learning situation, will also facilitate the recovery of pre-operatively learned brightness discrimination in rats with visual neocortical injuries.

D000647	Amnesia	Pathologic partial or complete loss of the ability to recall past experiences (AMNESIA, RETROGRADE) or to form new memories (AMNESIA, ANTEROGRADE). This condition may be of organic or psychologic origin. Organic forms of amnesia are usually associated with dysfunction of the DIENCEPHALON or HIPPOCAMPUS.

D000648	Amnesia, Retrograde	Loss of the ability to recall information that had been previously encoded in memory prior to a specified or approximate point in time. This process may be organic or psychogenic in origin. Organic forms may be associated with CRANIOCEREBRAL TRAUMA; CEREBROVASCULAR ACCIDENTS; SEIZURES; DEMENTIA; and a wide variety of other conditions that impair cerebral function.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
