Synedrella nodiflora Extract Depresses Excitatory Synaptic Transmission and Chemically-Induced In Vitro Seizures in the Rat Hippocampus

Frontiers in Pharmacology, 2021
Extracts of the tropical Cinderella plant Synedrella nodiflora are used traditionally to manage convulsive conditions in the West African sub-region.

Imbalance of Excitation and Inhibition at Threshold Level In the Auditory Cortex

Frontiers in Neural Circuits, 2015
The interplay of cortical excitation and inhibition is a fundamental feature of cortical information processing. Excitation and inhibition in single cortical neurons are balanced in their response to optimal sensory stimulation due to thalamocortical ...

Feed-forward recruitment of electrical synapses enhances synchronous spiking in the mouse cerebellar cortex

eLife, 2020
In the cerebellar cortex, molecular layer interneurons use chemical and electrical synapses to form subnetworks that fine-tune the spiking output of the cerebellum.

Cholinergic and Noradrenergic Modulation of Corticothalamic Synaptic Input From Layer 6 to the Posteromedial Thalamic Nucleus in the Rat

Frontiers in Neural Circuits, 2021
Cholinergic and noradrenergic neuromodulation of the synaptic transmission from cortical layer 6 of the primary somatosensory cortex to neurons in the posteromedial thalamic nucleus (PoM) was studied using an in vitro slice preparation from young rats ...

Anterograde Activin signaling regulates postsynaptic membrane potential and GluRIIA/B abundance at the Drosophila neuromuscular junction. [PDF]

PLoS ONE, 2014
Members of the TGF-β superfamily play numerous roles in nervous system development and function. In Drosophila, retrograde BMP signaling at the neuromuscular junction (NMJ) is required presynaptically for proper synapse growth and neurotransmitter ...

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.

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

It is time to combine the two main traditions in the research on the neural correlates of consciousness: C=LxD

Frontiers in Psychology, 2014
Research on neural correlates of consciousness has been conducted and carried out mostly from within two relatively autonomous paradigmatic traditions – studying the specific contents of conscious experience and their brain-process correlates and ...

Patch-clamp analysis of nicotinic synapses whose strength straddles the firing threshold of rat sympathetic neurons

Frontiers in Neuroscience, 2022
Neurons in paravertebral sympathetic ganglia are innervated by converging nicotinic synapses of varying strength. Based upon intracellular recordings of excitatory postsynaptic potentials (EPSPs) with sharp microelectrodes these synapses were classified ...
