The effect of Urtica dioica extract on the number of astrocytes in the dentate gyrus of diabetic rats [PDF]

open access: yes, 2009
Diabetes mellitus is associated with cerebral alterations in both human and animal models of the disease. These alterations include abnormal expression of hypothalamic neuropeptides and hippocampal astrogliosis.

Remifentanil alleviates transient cerebral ischemia-induced memory impairment through suppression of apoptotic neuronal cell death in gerbils [PDF]

open access: yesKorean Journal of Anesthesiology, 2011
BackgroundDuring neurosurgical procedures, patients are often exposed to hypoxic and ischemic brain damage. Cerebral ischemia leads to neuronal cell death and eventually causes neurological impairments.

Enhanced hippocampal long-term potentiation and spatial learning in aged 11ß-hydroxysteroid dehydrogenase type 1 knock-out mice [PDF]

open access: yes, 2007
Glucocorticoids are pivotal in the maintenance of memory and cognitive functions as well as other essential physiological processes including energy metabolism, stress responses, and cell proliferation.

Dynamic expression of lamin B1 during adult neurogenesis in the vertebrate brain

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background In mammals, specific brain regions such as the dentate gyrus (DG) of the hippocampus and the subventricular zone (SVZ) of the lateral ventricles harbor adult neural stem/progenitor cells (ANSPCs) that give rise to new neurons and contribute to structural and functional brain plasticity.

Subfield-specific interneuron circuits govern the hippocampal response to novelty in male mice

open access: yesNature Communications
The hippocampus is the brain’s center for episodic memories. Its subregions, the dentate gyrus and CA1-3, are differentially involved in memory encoding and recall. Hippocampal principal cells represent episodic features like movement, space, and context,

The granule cell density of the dentate gyrus following administration of Urtica dioica extract to young diabetic rats [PDF]

open access: yes, 2008
Urtica dioica L. Stinging nettle has long been known worldwide as a medicinal plant. To study the benefits of the nettle in diabetic encephalopathy, the granule cell density of the dentate gyrus of diabetic rats was studied following administration of ...

How informative are spatial CA3 representations established by the dentate gyrus? [PDF]

open access: yes, 2009
In the mammalian hippocampus, the dentate gyrus (DG) is characterized by sparse and powerful unidirectional projections to CA3 pyramidal cells, the so-called mossy fibers. Mossy fiber synapses appear to duplicate, in terms of the information they convey,

Usp9x-deficiency disrupts the morphological development of the postnatal hippocampal dentate gyrus

open access: yesScientific Reports, 2016
Within the adult mammalian brain, neurogenesis persists within two main discrete locations, the subventricular zone lining the lateral ventricles and the hippocampal dentate gyrus.

Exercise-Induced Activated Platelets Increase Adult Hippocampal Precursor Proliferation and Promote Neuronal Differentiation

open access: yesStem Cell Reports, 2019
Summary: Physical activity is a strong positive physiological modulator of adult neurogenesis in the hippocampal dentate gyrus. Although the underlying regulatory mechanisms are still unknown, systemic processes must be involved.
