Extended Interneuronal Network of the Dentate Gyrus [PDF]
Cell Reports, 2017 Local interneurons control principal cells within individual brain areas, but anecdotal observations indicate that interneuronal axons sometimes extend beyond strict anatomical boundaries. Here, we use the case of the dentate gyrus (DG) to show that boundary-crossing interneurons with cell bodies in CA3 and CA1 constitute a numerically significant and ...

Dentate gyrus and spatial behaviour
Progress in Neuro-Psychopharmacology and Biological Psychiatry, 2009 This article reviews evidence from studies employing colchicine-induced granule cell loss in the adult rat brain, and irradiation-induced hypoplasia of the neonatal dentate gyrus, on the performance of spatial and non-spatial behavioral tasks. The general picture emerging from this analysis reveals that the dentate gyrus granule cells are critically ...

Neuromodulation of the Feedforward Dentate Gyrus-CA3 Microcircuit [PDF]
Frontiers in Synaptic Neuroscience, 2016 The feedforward dentate gyrus-CA3 microcircuit in the hippocampus is thought to activate ensembles of CA3 pyramidal cells and interneurons to encode and retrieve episodic memories. The creation of these CA3 ensembles depends on neuromodulatory input and synaptic plasticity within this microcircuit.

Capicua regulates the development of adult-born neurons in the hippocampus
Scientific Reports, 2021 New neurons continuously arise from neural progenitor cells in the dentate gyrus of the adult hippocampus to support ongoing learning and memory formation.

Evolution of the mammalian dentate gyrus [PDF]
Journal of Comparative Neurology, 2015 ABSTRACTThe dentate gyrus (DG), a part of the hippocampal formation, has important functions in learning, memory, and adult neurogenesis. Compared with homologous areas in sauropsids (birds and reptiles), the mammalian DG is larger and exhibits qualitatively different phenotypes: 1) folded (C‐ or V‐shaped) granule neuron layer, concave toward the hilus

p16Ink4a Prevents the Activation of Aged Quiescent Dentate Gyrus Stem Cells by Physical Exercise
Frontiers in Cellular Neuroscience, 2019 In the neurogenic niches—the dentate gyrus of the hippocampus and the subventricular zone (SVZ) adjacent to lateral ventricles—stem cells continue to divide during adulthood, generating progenitor cells and new neurons, and to self-renew, thus ...

Adult-born neurons add flexibility to hippocampal memories
Frontiers in Neuroscience, 2023 Although most neurons are generated embryonically, neurogenesis is maintained at low rates in specific brain areas throughout adulthood, including the dentate gyrus of the mammalian hippocampus.

Endocannabinoids in the dentate gyrus [PDF]
, 2007 Recent years have produced rapid and enormous growth in our understanding of endocannabinoid-mediated signaling in the CNS. While much of the recent progress has focused on other areas of the brain, a significant body of evidence has developed that indicates the presence of a robust system for endocannabinoid-mediated signaling in the dentate gyrus ...

Advanced Science, EarlyView.This study investigates the role of group 2 innate lymphoid cells (ILC2) in the choroid plexus (ChP) following traumatic brain injury (TBI). ILC2 accumulation alleviates immune infiltration, preserves hippocampal integrity, and improves sensory‐motor and memory functions.
