Retrograde amnesia for spatial information: a dissociation between intra and extramaze cues following hippocampus lesions in rats

    The European journal of neuroscience
  • 1 October 1998
TLDR
The results indicate that the hippocampus is critical for the storage and/or retrieval of spatial reference information that was learned up to 1 month before hippocampus damage; however, in the absence of the hippocampus, efficient retention can still occur provided that the spatial knowledge was learned in a simple associative manner.
Patterns of interhemispheric correlation during human communication.
TLDR
The interhemispheric correlation patterns for each subject were observed to become similar during the communication sessions as compared to the control situations, and these effects are not due to nonspecific factors such as habituation or fatigue.
Essential role of the perirhinal cortex in complex tactual discrimination tasks in rats.

TLDR
The findings suggest that the Prh plays an essential role in somatosensory perceptual functions and a reversal learning task revealed a profound deficit in the initial learning phase, but unimpaired learning in the reversal phase with identical stimuli.

Perirhinal cortex lesions produce retrograde amnesia for spatial information in rats: consolidation or retrieval?

  • 1 August 2008
TLDR
The differential contribution of various regions of the medial temporal lobe to memory is demonstrated, suggesting that the perirhinal cortex plays a key role in the retrieval of spatial information for a long period of time.
The hippocampus and flexible spatial knowledge in rats
TLDR
The results suggest that when the hippocampus is damaged a preserved highly inflexible egocentric strategy is employed to solve the spatial problem.
