The dentate gyrus (DG) is a "V" shaped structure, situated in the most proximal part of the hippocampal formation. It borders with field CA3 of the cornu ammonis.
In this description of the stratification/lamination of the dentate gyrus, the most superficial layer, close to the pial surface of the brain comes first, followed by the layers below.
In-between the granule cell layer and the polymorphic layer lies a narrow strip of cells that is termed the subgranular zone. The cells in the subgranular zone are linked to adult neurogenesis. See: Steven A Goldman & Zhuoxun Chen, 2011
For a review of the ultrastructure and synaptic connectivity of cell types in the adult rat dentate gyrus, see: Ribak et al, 2007. Another good overview, more tailored towards interneurons is given by Freund and Buzsaki, 1996. An online repository is available at: www.hippocampome.org.
