Dentate Gyrus Added 385,000 Granule Neurons Despite Neuron Turnover
TL;DR: A 2026 rat study in Hippocampus found that the dentate gyrus (DG), a hippocampal memory region, gained about 385,000 granule neurons from 2 to 18 months of age even though older development-born neurons were also being lost. Key Findings 385,000-cell net gain: Total DG granule neuron counts increased by about 385,000 cells from 2 …
