Animal Models and Experimental Medicine, EarlyView.Systematic process of collecting studies based on PRISMA. Abstract Background Due to the widespread use of cell phone devices today, numerous research studies have focused on the adverse effects of electromagnetic radiation on human neuropsychological and reproductive systems.

Analysis of the intraspinal calcium dynamics and its implications on the plasticity of spiking neurons [PDF]
, 2003 The influx of calcium ions into the dendritic spines through the N-metyl-D-aspartate (NMDA) channels is believed to be the primary trigger for various forms of synaptic plasticity. In this paper, the authors calculate analytically the mean values of the calcium transients elicited by a spiking neuron undergoing a simple model of ionic currents and back-

Two-trace model for spike-timing-dependent synaptic plasticity [PDF]
Neural Computation 2015, 27(3), 672-698, 2014 We present an effective model for timing-dependent synaptic plasticity (STDP) in terms of two interacting traces, corresponding to the fraction of activated NMDA receptors and the Ca2+ concentration in the dendritic spine of the postsynaptic neuron.

Glutamate-induced depression of EPSP–spike coupling in rat hippocampal CA1 neurons and modulation by adenosine receptors [PDF]
, 2010 The presence of high concentrations of glutamate in the extracellular fluid following brain trauma or ischaemia may contribute substantially to subsequent impairments of neuronal function.

Purine Metabolism and Dystonia: Perspectives of a Long‐Promised Relationship
Annals of Neurology, EarlyView.Purine pool imbalance in purine metabolism disorders, such as Lesch–Nyhan disease, intersects with dystonia pathogenesis. The recent discovery of gain‐of‐function IMPDH2 pathogenic variants in patients with prominent dystonic manifestations provides new insights into the link between dystonia and purinergic system defects.

Neurodegeneration in multiple sclerosis
WIREs Mechanisms of Disease, Volume 15, Issue 1, January/February 2023., 2023 Chronic demyelination results in impaired axon metabolism and function, ultimately leading to progressive neurological decline. Neuroprotective strategies aim to protect axons from inflammatory‐mediated destruction, thereby improving axonal integrity and clinical disability (Image created in BioRender.com).

A single psychotomimetic dose of ketamine decreases thalamocortical spindles and delta oscillations in the sedated rat [PDF]
arXiv, 2020 Background: In patients with psychotic disorders, sleep spindles are reduced, supporting the hypothesis that the thalamus and glutamate receptors play a crucial etio-pathophysiological role, whose underlying mechanisms remain unknown. We hypothesized that a reduced function of NMDA receptors is involved in the spindle deficit observed in schizophrenia.

Quantifying constraints determining independent activation on NMDA receptors mediated currents from evoked and spontaneous synaptic transmission at an individual synapse [PDF]
arXiv, 2022 A synapse acts on neural transmission through a chemical process called synapses fusion between pre-synaptic and post-synaptic terminals. Presynaptic terminals release neurotransmitters either in response to action potential or spontaneously independent of presynaptic activity.

Imbalance of p75(NTR)/TrkB protein expression in Huntington's disease: Implication for neuroprotective therapies [PDF]
, 2013 Neuroprotective therapies based on brain-derived neurotrophic factor (BDNF) administration have been proposed for Huntington's disease (HD) treatment. However, our group has recently reported reduced levels of TrkB in HD mouse models and HD human brain ...
