Enhancement of monosynaptic excitatory postsynaptic potentials by glutamate in frog spinal motoneurons

Brain Research, 1993
We analyzed glutamate-induced enhancement of the amplitude of monosynaptic excitatory postsynaptic potentials evoked by stimulation of the lateral column fibers (LC-EPSPs) on lumbar motoneurons in the frog spinal cord. Low concentrations (0.1-0.3 mM) of glutamate, which produced small depolarization, often enhanced EPSP associated with inhibition of a ...

Excitatory and inhibitory postsynaptic potentials in cat hypoglossal motoneurons during swallowing

Experimental Brain Research, 1988
The postsynaptic potentials produced in cat genioglossus and styloglossus motoneurons (GG- and SG-Mns) during swallowing were studied. During swallowing elicited by placing water on the dorsum of the tongue, the GG-muscle discharged for 80-210 ms (mean +/- S. D.

5-Hydroxytryptamine depresses reticulospinal excitatory postsynaptic potentials in motoneurons of the lamprey

Neuroscience Letters, 1991
Application of 5-hydroxytryptamine (5-HT) to the lamprey spinal cord in vitro reversibly depressed the chemical component of excitatory post-synaptic potentials recorded intracellularly in motoneurons and evoked by stimulation of single reticulospinal Müller cells. The depression could be produced either by local application of small volumes of 10 mM 5-

Partitioning of monosynaptic Ia excitatory postsynaptic potentials in the motor nucleus of the cat lateral gastrocnemius muscle.

Journal of Neurophysiology, 1986
Experiments were conducted to test the hypothesis that a partitioning of Ia monosynaptic excitatory postsynaptic potentials (Ia EPSPs) is present in motor nuclei supplying muscles with regions capable of different mechanical actions.

Ghrelin Potentiates Miniature Excitatory Postsynaptic Currents in Supraoptic Magnocellular Neurones

Journal of Neuroendocrinology, 2009
Ghrelin is an orexigenic peptide discovered in the stomach as a ligand of the orphan G‐protein coupled receptor, and participates in the regulation of growth hormone (GH) release. Previous studies have demonstrated that ghrelin suppressed water intake and stimulated the secretion of arginine vasopressin in rats. We examined the effect of ghrelin on the

Adenosine inhibits the NMDA receptor-mediated excitatory postsynaptic potential in the hippocampus

Brain Research, 1993
The effect of the stable adenosine analogue 2-chloroadenosine (CADO) on the component of the field excitatory postsynaptic potential (fepsp) mediated by the N-methyl-D-aspartate (NMDA) type of glutamate receptor was studied in the hippocampal CA1 area of the rat.

Anoxic depression of excitatory and inhibitory postsynaptic potentials in rat neocortical slices

Journal of Neurophysiology, 1993
1. The effects of brief anoxia (4-6 min replacement of O2 by N2) on synaptic potentials evoked from layer IV and/or the white matter were studied in pyramidal neurons of layers II-III from rat neocortical slices. 2. The early and late components of excitatory postsynaptic potentials (EPSPs) showed differential sensitivity to anoxia: within 2 min the ...

2-Deoxy-D-glucose-induced changes in membrane potential, input resistance, and excitatory postsynaptic potentials of CA1 hippocampal neurons.

Canadian Journal of Physiology and Pharmacology, 1997
Temporary block of glycolysis by 2-deoxy-D-glucose (2-DG) reversibly suppresses synaptic transmission in the CA1 region of hippocampal slices. Recovery of responses is followed by a sustained potentiation of field excitatory postsynaptic potentials ...

Integration of excitatory postsynaptic potentials in dendrites of motoneurons of rat spinal cord slice cultures.

Journal of Neurophysiology, 1998
We examined the attenuation and integration of spontaneous excitatory postsynaptic potentials (sEPSPs) in the dendrites of presumed motoneurons (MNs) of organotypic rat spinal cord cultures.

Generation of excitatory postsynaptic potentials in the hippocampus after functional modification of glycosaminoglycans

Bulletin of Experimental Biology and Medicine, 2008
Experiments on hippocampal slices form 4-week-old rats (n=28) showed that addition of lidase (1.0 and 10.0 U/ml) to the perfusion solution (artificial cerebrospinal fluid) was accompanied by the impaired generation or blockade of excitatory postsynaptic potentials and population spikes in the hippocampal CA1 region during stimulation of Schaffer ...
