Recurrent excitatory postsynaptic potentials induced by synchronized fast cortical oscillations [PDF]
Proceedings of the National Academy of Sciences, 1997 Gamma frequency (about 20–70 Hz) oscillations occur during novel sensory stimulation, with tight synchrony over distances of at least 7 mm. Synchronization in the visual system has been proposed to reflect coactivation of different parts of the visual field by a single spatially extended object.

A glibenclamide-sensitive TRPM4-mediated component of CA1 excitatory postsynaptic potentials appears in experimental autoimmune encephalomyelitis [PDF]
Scientific Reports, 2022 The transient receptor potential melastatin 4 (TRPM4) channel contributes to disease severity in the murine experimental autoimmune encephalomyelitis (EAE) model of multiple sclerosis and to neuronal cell death in models of excitotoxicity and traumatic ...

Compressed Sensing of Excitatory Postsynaptic Potential Bio-Signals
Computer Science & Information Technology ( CS & IT ), 2016 To reduce the size of the biosignal data is important because a huge amount of data is made by various experiments. In the paper, we efficiently compress the excitatory postsynaptic potentials (EPSPs) which is one of the biosignal types. To the best of authors' knowledge, EPSPs compression has not been studied yet.

Data compression of excitatory postsynaptic potentials [PDF]
Electronics Letters, 2015 Reducing the size of biosignal data is important because a huge amount of data is made by various experiments. In this reported work excitatory postsynaptic potentials (EPSPs) which are one of the biosignal types are efficiently compressed. To the best of authors’ knowledge, EPSPs compression has not been studied yet. The EPSP signal has a feature that

γ-Hydroxybutyrate inhibits excitatory postsynaptic potentials in rat hippocampal slices
European Journal of Pharmacology, 1999 Gamma-Hydroxybutyrate (GHB) has been shown to mimic different central actions of ethanol, to suppress alcohol withdrawal syndrome, and to reduce alcohol consumption both in rats and in humans. The aim of the present study was to determine if GHB shared with alcohol the ability to inhibit glutamate action at both NMDA and AMPA/kainate receptors.

Hyperpolarization following activation of K+ channels by excitatory postsynaptic potentials [PDF]
Nature, 1983 We have postulated that an excitatory postsynaptic potential (e.p.s.p.) may open voltage-sensitive K+ ('M') channels, in an appropriate depolarizing range, and that this could alter the e.p.s.p. waveform. Consequently, the fast e.p.s.p. in neurones of sympathetic ganglia, elicited by a nicotinic action of acetylcholine (ACh), could be followed by a ...

Active summation of excitatory postsynaptic potentials in hippocampal CA3 pyramidal neurons [PDF]
Proceedings of the National Academy of Sciences, 1998 The manner in which the thousands of synaptic inputs received by a pyramidal neuron are summed is critical both to our understanding of the computations that may be performed by single neurons and of the codes used by neurons to transmit information. Recent work on pyramidal cell dendrites has shown that subthreshold synaptic inputs are modulated by ...

Neuropharmacology, 1997 By intracellular and whole cell recording in rat brain slices, it was found that bath-applied serotonin (5-HT) produces an increase in the frequency and amplitude of spontaneous excitatory postsynaptic potentials/currents (EPSPs/EPSCs) in layer V pyramidal cells of neocortex and transitional cortex (e.g. medial prefrontal, cigulate and frontoparietal).

A Simple Mathematical Model of Second-Messenger Mediated Slow Excitatory Postsynaptic Potentials
Journal of Computational Neuroscience, 2000 We have developed a novel and simple mathematical model of a slow excitatory postsynaptic potential (EPSP) based on an abstraction of the processes of activation, inactivation, and summation of a cAMP, protein kinase A (PKA)-dependent second-messenger cascade.
