WebJul 2, 2024 · In the mammalian adult hippocampus, new neurons are continuously generated throughout life in the subgranular zone of the dentate gyrus. Increasing evidence point out the contribution of adult-born hippocampal granule cells (GCs) to cognitive processes such as learning and memory, indicating the relevance of understanding the … WebKim et al. show cell-type-specific properties of spatial firing in the dentate gyrus by recording from single cells as mice freely explored distinct environments. These findings support the role of both granule cells and mossy cells in global remapping and orthogonalization (pattern separation) of spatial representations in dentate gyrus.

WebThe dentate gyrus and entorhinal cortex (EC) are the gateway to the hippocampus. These regions in patients with temporal lobe epilepsy display neuropathological changes that may contribute to seizure activity. Potentially important epileptogenic factors include inadequate inhibition of dentate granule cells and layer II cells in the medial ... TrkB is responsible for the maintenance of normal synaptic connectivity of the dentate granule cells. TrkB also regulates the specific morphology (biology) of the granule cells and is thus said to be important in regulating neuronal development, neuronal plasticity, learning, and the development of epilepsy. The TrkB regulation of granule cells is important in preventing memory deficits and limbic epilepsy. This is due to the fact that dentate granule cells play a critical role i…
