Abstract:
The hippocampus is critical to declarative memory in humans
and spatial memory in rodents. Our research attempts to bridge
between these two characterizations of hippocampal dependent
memory, and in doing so reveal fundamental cognitive and neural
coding mechanisms that are common to both. I will present evidence
that the hippocampus is critical to the establishment of a
systematic organization of memories and to flexible expression of
memory. In addition, I will present evidence that hippocampal
neurons encode a broad range of experience and that these codings
may be organized as representations of episodes in memory. I will
suggest that these episodic codings are linked by common elements
to construct an organized representation of acquired
knowledge.
