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-

A Molecularly Defined Medullary Network for Control of Respiratory Homeostasis

Advanced Science, EarlyView.
The dynamic interplay between central respiratory chemoreceptors and the respiratory central pattern generator is essential for maintaining stable respiratory rhythm and patterns, particularly during sleep. This study offers novel insights into the anatomical, molecular, and functional characteristics of a medullary network involving the nucleus ...

A Ca2+-based computational model for NDMA receptor-dependent synaptic plasticity at individual post-synaptic spines in the hippocampus

Frontiers in Synaptic Neuroscience, 2010
Associative synaptic plasticity is synapse specific and requires coincident activity in presynaptic and postsynaptic neurons to activate NMDA receptors (NMDARs). The resultant Ca2+ influx is the critical trigger for the induction of synaptic plasticity.

Massage‐Mimicking Nanosheets Mechanically Reorganize Inter‐organelle Contacts to Restore Mitochondrial Functions in Parkinson's Disease

Advanced Science, EarlyView.
Parkinson's disease (PD) progression is aggravated by disrupted inter‐organelle contacts, which are influenced by mechanical forces. NanoMassage, 200 nm PEGylated black phosphorus nanosheets, deliver targeted mechanical stimulation to neural cells.

PAF‐induced inflammatory and immuno‐allergic ophthalmic diseases and their mitigation with PAF receptor antagonists: Cell and nuclear effects

BioFactors, Volume 48, Issue 6, Page 1226-1249, November/December 2022., 2022
Abstract Ocular allergies are becoming more prevalent as more airborne pollutants, irritants and microbes pervade our environment. Inflammatory and allergic mediators released by dendritic and mast cells within the conjunctiva cause allergic conjunctivitis (AC), a prevalent ocular surface disorder that affects >40% of the world's human population on a ...

Therapeutic Delivery of circDYM by Perillyl Alcohol Nanoemulsion Alleviates LPS‐Induced Depressive‐Like Behaviors

Advanced Science, EarlyView.
PANEs are specifically designed to enhance the brain delivery efficiency of circDYM compared to commercialized lipid nanoparticles (LNPs). Intranasal administration of PANE‐circDYM effectively alleviated LPS‐induced depressive‐like behaviors by mitigating neuroinflammation and promoting neuroplasticity.

Distinguishing between Presynaptic and Postsynaptic Mechanisms of Short-Term Depression during Action Potential Trains

Journal of Neuroscience, 2003
Short-term facilitation and depression have a profound influence on transmission at many glutamatergic synapses, particularly during trains of stimuli. A major component of these processes is postsynaptic receptor desensitization.

Altered Neural Activity in the Mesoaccumbens Pathway Underlies Impaired Social Reward Processing in Shank3‐Deficient Rats

Advanced Science, EarlyView.
This study examines the effects of Shank3 mutation on the mesoaccumbens pathway using a Shank3‐deficient rat model. The findings reveal altered social reward processing in these rats, accompanied by changes in dopaminergic and GABAergic neural activity within the ventral tegmental area (VTA) and dopamine release in the nucleus accumbense (NAc ...

Single dendrite-targeting interneurons generate branch-specific inhibition.

Frontiers in Neural Circuits, 2014
Microcircuits composed of dendrite-targeting inhibitory interneurons and pyramidal cells are fundamental elements of cortical networks, however, the impact of individual interneurons on pyramidal dendrites is unclear.
