EC-hippocampus system

The entorhinal cortex (EC) is a major part of the hippocampal formation of the brain, and is reciprocally connected with the hippocampus.

The hippocampal formation, which consists of the hippocampus, perirhinal cortex, the dentate gyrus, the subicular areas and the EC forms one of the most important parts of the limbic system. The entorhinal cortex is an infolding of the parahippocampal gyrus into the inferior (temporal) horn of the lateral ventricle.
