Retrograde amnesia.
In humans, the phenomenon of temporally graded retrograde amnesia has been described in the clinic and the laboratory for more than 100 years. In the 1990s, retrograde amnesia began to be studied prospectively in experimental animals. We identified 13 published studies in which animals were given equivalent training at two or more separate times before damage to the fornix or hippocampal format...
متن کاملPerirhinal cortex lesions produce variable patterns of retrograde amnesia in rats.
Two experiments examined the contribution of the perirhinal cortex (PRh) to retrograde memory for the location of a platform in a water maze. In a previous study, we found that electrolytic lesions of the PRh produced retrograde amnesia, without a temporal gradient, for water-maze problems acquired 4 weeks and 2 days before surgery [Behav. Brain. Res. 114 (2000) 119]. In Experiment 1, we used t...
متن کاملRetrograde amnesia in Parkinson's disease.
Retrograde amnesia was assessed in demented and non-demented Parkinson's patients using a test of remote memory spanning the years from 1920-1979. Results indicated that the demented patients 1) scored significantly below normal controls and 2) had equal impairment for all time periods. This pattern was like that seen in other dementing illnesses (i.e., Huntington's and Alzheimer's diseases), b...
متن کاملPerirhinal cortex lesions produce retrograde amnesia for spatial information in rats: consolidation or retrieval?
Several lines of evidence in humans and experimental animals suggest that the hippocampus is critical for the formation and retrieval of spatial memory. However, although the hippocampus is reciprocally connected to adjacent cortices within the medial temporal lobe and they, in turn, are connected to the neocortex, little is known regarding the function of these cortices in memory. Here, using ...
متن کاملKetamine induces anterograde and retrograde amnesia in rats
Introduction: The N-methyl-D-aspartate (NMDA) receptors, which have been implicated in memory formation, could be noncompetitively blocked by ketamine. The present study examines the short term effect of ketamine on induction of anterograde and retrograde amnesia in male rats using Morris water maze (MWM). Methods: Male N-MRI rats were randomly divided into nine experimental groups. MWM stud...
