Dentate Gyrus

The dentate gyrus is one of the few regions in the brain where adult neurogenesis has been confirmed. It may play an important role in translating neural codes for creating memories.

The hippocampal formation has three regions, which are highly interconnected: the dentate gyrus, CA3, and CA1. It is one of the very few regions in the brain where adult neurogenesis (development of new neurons) has been confirmed. The dentate gyrus may play an important role in translating complex neural codes from cortical areas into simper code that can be used by the hippocampus to form new memories.
