Hippocampus

Sachin S. Deshmukh, James J. Knierim
2012 Wiley Interdisciplinary Reviews: Cognitive Science  
Damage to the hippocampus and related brain regions causes a profound amnesic syndrome, in which patients are unable to form new memories about their experiences and about facts about the world.  ...  The theories that are currently most influential propose that the hippocampus is the substrate of declarative or episodic memory and that the hippocampus is the neural locus of a cognitive map.  ...  Thus, the long-term stabilization of new place fields was selectively affected by CPP, without hindering the formation of the place fields in new environments.  ...

On the neural bases of the spatial mapping system: Hippocampus vs. hippocampal formation

Leonard E. Jarrard

Hippocampal and cortical place cell plasticity: Implications for episodic memory

Loren M. Frank, Emery N. Brown, Garrett B. Stanley
2006 Hippocampus  
In humans, the hippocampus is essential for storing episodic memories.  ...  We found that hippocampal place fields exhibited three phenomena that may have direct relevance to the encoding of episodic memories: (1) very rapid plasticity upon exposure to the new environment, (2)  ...  This finding may help explain why the hippocampus is essential for the formation of new episodic memories.  ...
