ABSTRACT

The hippocampus has been proven to be important for episodic memory and spatial memory. As the structure and connectivity of the hippocampus have been clear, and because of the abundance of the connectivity and cerebral functions regarding hippocampus, multiple models on the localization of hippocampal functions have been proposed. The AT/PM (anterior temporal/posterior medial) model proposed that different parts of hippocampus might process different kinds of information, the computational model proposed that different subfields of hippocampus perform different procedures on information, and the gradient model proposed that different parts of hippocampus would do the latter function. While the models seem diverse from one another, there might be connections that could unify the models. We attempt to explain and rationalize the connections among the models, yet there are still contradictions that would need further research to resolve.
