Remote spatial memory and the hippocampus: effect of early and extensive training in the radial maze.

25 Aug 2009 In a previous study we showed a temporally graded retrograde amnesia after hippocampal lesions when rats learned a spatial reference memory task in which two types of signals simultaneously indicated the goal arm (shape of the experimental room and ... Read more...

Making context memories independent of the hippocampus.

22 Jun 2009 We present evidence that certain learning parameters can make a memory, even a very recent one, become independent of the hippocampus. We confirm earlier findings that damage to the hippocampus causes severe retrograde amnesia for context memories, ... Read more...

Functional differentiation and cooperation among the hippocampal subregions in rats to effect spatial memory processes.

6 Jun 2009 We investigated the roles of the hippocampal subregions and intrahippocampal networks in effecting spatial reference and working processes. The results showed that the dentate gyrus plays a key role in encoding both types of spatial memory. Lesions ... Read more...

Technical information about 'Hippocampus'

Definition: A curved elevation of gray matter extending the entire length of the floor of the temporal horn of the lateral ventricle (Dorland, 28th ed). The hippocampus, subiculum, and DENTATE GYRUS constitute the hippocampal formation. Sometimes authors include the ENTORHINAL CORTEX in the hippocampal formation.
