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 ...

ANALYSIS OF THE SLOW EXCITATORY POSTSYNAPTIC POTENTIAL IN BULLFROG SYMPATHETIC GANGLION CELLS
The Japanese Journal of Physiology, 1976 The ionic mechanism of the slow excitatory postsynaptic potential (slow EPSP), i.e. the muscarinic action of acetylcholine (ACh), was studied either by stimulating preganglionic nerves or by applying ACh in curarized sympathetic ganglion cells of bullfrogs.

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.

Compressed Sensing of Excitatory Postsynaptic Potential Bio-Signals [PDF]
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.

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 ...

Data compression of excitatory postsynaptic potentials
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

A slow excitatory postsynaptic potential mediated by 5-HT2 receptors in nucleus prepositus hypoglossi [PDF]
Journal of Neuroscience, 1994 Intracellular recordings were made from neurons of the nucleus prepositus hypoglossi in slices of guinea pig medulla. 5-HT (serotonin) caused a hyperpolarization followed by a late depolarization.

Synaptic potentiation of dual‐component excitatory postsynaptic currents in the rat hippocampus. [PDF]
The Journal of Physiology, 1995 1. Whole‐cell patch‐clamp recording has been used to study tetanus‐induced synaptic potentiation of dual‐component excitatory postsynaptic currents (EPSCs) in the CA1 region of rat hippocampal slices, following blockade of GABAA and GABAB receptor‐mediated synaptic inhibition. 2.
