It is the segment of the neocortex that constitutes a part of the hippocampal formation and is involved in crucial processes of learning, memory, and neurogenesis.
Dentate gyrus is composed of gray matter and makes an important part of hippocampal formation. It is tooth shaped and located between the fimbriae of the hippocampus and the parahippocampal gyrus (Snell 2010). It is located underneath the temporal lobe. The hippocampus formation consists of three elements, namely, the cornu ammonis (collectively known as the hippocampus), the dentate gyrus, and subiculum (Barrett et al. 2009; Kandel et al. 2000; Nicholls et al. 2001). The hippocampal formation forms the floor of the temporal horn of the lateral ventricle, along with other associated regions (Kandel et al. 2000). The dentate gyrus interlocks with the hippocampus, and forms a C-shaped structure, the subiculum adjoining it (Nicholls et...
