Evolution of the mammalian dentate gyrus [PDF]

Journal of Comparative Neurology, 2016
The 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 ...

Radial glial cells in the adult dentate gyrus: what are they and where do they come from? [version 1; referees: 2 approved]

F1000Research, 2018
Adult neurogenesis occurs in the dentate gyrus in the mammalian hippocampus. These new neurons arise from neural precursor cells named radial glia-like cells, which are situated in the subgranular zone of the dentate gyrus.

Neurogenesis in the dentate gyrus: carrying the message or dictating the tone

Frontiers in Neuroscience, 2013
The dentate gyrus is a region in the mammalian brain critical for memory encoding with a neuronal architecture and function that deviates considerably from other cortical areas.

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 ...

Structure, function, and plasticity of hippocampal dentate gyrus microcircuits

Frontiers in Neural Circuits, 2014
The hippocampus mediates several higher brain functions, such as learning, memory, and spatial coding. The input region of the hippocampus, the dentate gyrus, plays a critical role in these processes.

Gamma rhythm communication between entorhinal cortex and dentate gyrus neuronal assemblies

Science, 2021
Brain region coordination in learning Gamma-frequency oscillations have been hypothesized as a physiological mechanism of interregional communication in the brain.

MGluR5 mediates the interaction between late-LTP, network activity, and learning. [PDF]

PLoS ONE, 2008
Hippocampal synaptic plasticity and learning are strongly regulated by metabotropic glutamate receptors (mGluRs) and particularly by mGluR5. Here, we investigated the mechanisms underlying mGluR5-modulation of these phenomena.

Enigmas of the Dentate Gyrus [PDF]

Neuron, 2007
We are rapidly approaching a better understanding of the mechanisms that allow our brains to form distinct representations for similar events or episodes. McHugh et al. have brought that goal one step closer by showing that NMDA receptor-dependent synaptic plasticity in the dentate gyrus is necessary for immediate differentiation between environments ...

Novel control by the CA3 region of the hippocampus on neurogenesis in the dentate gyrus of the adult rat. [PDF]

PLoS ONE, 2011
The dentate gyrus is a site of continued neurogenesis in the adult brain. The CA3 region of the hippocampus is the major projection area from the dentate gyrus. CA3 sends reciprocal projections back to the dentate gyrus.
