The dentate gyrus efficiently converges LEC and MEC inputs into multimodal, highly specific and reliable environmental representations

This study reveals how the dentate gyrus gradually learns to integrate olfactory and spatial signals from the entorhinal cortex, transforming them into sparse and highly specific representations that improve with experience.
