The dentate gyrus: fundamental neuroanatomical organization (dentate gyrus for dummies)

Prog Brain Res. 2007:163:3-22. doi: 10.1016/S0079-6123(07)63001-5.


The dentate gyrus is a simple cortical region that is an integral portion of the larger functional brain system called the hippocampal formation. In this review, the fundamental neuroanatomical organization of the dentate gyrus is described, including principal cell types and their connectivity, and a summary of the major extrinsic inputs of the dentate gyrus is provided. Together, this information provides essential information that can serve as an introduction to the dentate gyrus--a "dentate gyrus for dummies."
