Impairment Mechanisms and Intervention Approaches for Aged Human Neuromuscular Junctions

open access: yesFrontiers in Molecular Neuroscience, 2020
The neuromuscular junction (NMJ) is a chemical synapse formed between a presynaptic motor neuron and a postsynaptic muscle cell. NMJs in most vertebrate species share many essential features; however, some differences distinguish human NMJs from others ...

Substance P-mediated slow excitatory postsynaptic potential elicited in dorsal horn neurons in vivo by noxious stimulation.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1991
The original proposal that substance P is involved in the regulation of nociceptive information at the first sensory synapse in the spinal cord has been substantiated by a wide range of evidence, but definitive support has been lacking, due primarily to ...

Occurrence of Ordered and Disordered Structural Elements in Postsynaptic Proteins Supports Optimization for Interaction Diversity

open access: yesEntropy, 2019
The human postsynaptic density is an elaborate network comprising thousands of proteins, playing a vital role in the molecular events of learning and the formation of memory.

Differential Effects of D-Cycloserine and ACBC at NMDA Receptors in the Rat Entorhinal Cortex Are Related to Efficacy at the Co-Agonist Binding Site. [PDF]

open access: yesPLoS ONE, 2015
Partial agonists at the NMDA receptor co-agonist binding site may have potential therapeutic efficacy in a number of cognitive and neurological conditions. The entorhinal cortex is a key brain area in spatial memory and cognitive processing.

Electrogenesis of the slow inhibitory postsynaptic potential in bullfrog sympathetic ganglia.

open access: yesThe Japanese Journal of Physiology, 1983
The ionic mechanisms of the slow surface positive (P)-potential and the slow inhibitory postsynaptic potential (IPSP), an intracellularly recorded P-potential in sympathetic ganglia, were analysed by means of sucrose-gap, intracellular microelectrode ...

Disinhibition of hippocampal CA3 neurons induced by suppression of an adenosine A1 receptor-mediated inhibitory tonus: Pre- and postsynaptic components [PDF]

open access: yes, 1993
Intracellular recordings were performed on hippocampal CA3 neuronsin vitro to investigate the inhibitory tonus generated by endogenously produced adenosine in this brain region.

GABAergic synaptic transmission regulates calcium influx during spike-timing dependent plasticity

open access: yesFrontiers in Synaptic Neuroscience, 2010
Coincident pre- and postsynaptic activity of hippocampal neurons alters the strength of gamma-aminobutyric acid (GABAA)-mediated inhibition through a Ca2+-dependent regulation of cation-chloride cotransporters.

Regulation of Irregular Neuronal Firing by Autaptic Transmission [PDF]

open access: yes, 2016
The importance of self-feedback autaptic transmission in modulating spike-time irregularity is still poorly understood. By using a biophysical model that incorporates autaptic coupling, we here show that self-innervation of neurons participates in the ...

Human synapses show a wide temporal window for spike-timing-dependent plasticity

open access: yesFrontiers in Synaptic Neuroscience, 2010
Throughout our lifetime, activity-dependent changes in neuronal connection strength enable the brain to refine neural circuits and learn based on experience.

Neuromodulation of Chemical Synaptic Transmission Driven by THz Photons

open access: yesResearch, 2022
Postsynaptic currents of chemical synapse are modulated by multitudinous neurotransmitters, such as acetylcholine, dopamine, glutamate, and γ-aminobutyric acid, many of which have been used in the treatment of neurological diseases.
