Assessments of dentate gyrus function: discoveries and debates
The dentate gyrus (DG) sits at the gateway to the hippocampus as the first stop along a trisynaptic loop that receives inputs from the cortex 1. In mammals such as rodents, the DG has garnered substantial attention as a site of adult neurogenesis — the continuous birth of neurons throughout adulthood — leading to exciting speculation as to ...
