Dentate Gyrus Research Paper

The entorhinal cortex serves as a main interface between the hippocampus and neocortex. The hippocampus and the entorhinal cortex are connected via pathways which play an important role in declarative memory formation. The hippocampus harbours the following subdivisions: 1). The dentate gyrus (DG) which is a tightly packed layer of small granule cells forming a v-shaped wedge. 2). Cornu Ammonis (CA) which mainly contain densely packed pyramidal cells (Hyman and Van Hoesen, 1987), emerge from the DG as: CA4, then CA3, then a very narrow transitional zone termed CA2 and then CA1 (refer Figure 10). The CA1 merges with the subiculum with projections leading back to the entorhinal cortex.
The entorhinal cortex contains 5 layers, amongst which Layer
