Bidirectional plasticity of excitatory postsynaptic potential (EPSP)-spike coupling in CA1 hippocampal pyramidal neurons

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2002
Integration of synaptic excitation to generate an action potential (excitatory postsynaptic potential-spike coupling or E-S coupling) determines the neuronal output.

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.

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 ...

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.

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.

Event-based update of synapses in voltage-based learning rules [PDF]

open access: yes, 2020
Due to the point-like nature of neuronal spiking, efficient neural network simulators often employ event-based simulation schemes for synapses. Yet many types of synaptic plasticity rely on the membrane potential of the postsynaptic cell as a third factor in addition to pre- and postsynaptic spike times.

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.

Paradoxical Results of Long-Term Potentiation explained by Voltage-based Plasticity Rule [PDF]

open access: yesFront. Synaptic Neurosci. (2020) 12:585539, 2020
Experiments have shown that the same stimulation pattern that causes Long-Term Potentiation in proximal synapses, will induce Long-Term Depression in distal ones. In order to understand these, and other, surprising observations we use a phenomenological model of Hebbian plasticity at the location of the synapse.
