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, 1988The 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.

Nicotinic cholinoceptor-mediated excitatory postsynaptic potentials in rat nucleus ambiguus
Experimental Brain Research, 1993In rat brainstem slice preparations, intracellular recording from neurons (n = 39) in the compact formation of the nucleus ambiguus (AMBc) revealed spontaneous and miniature excitatory postsynaptic potentials (EPSPs; n = 11) that, along with acetylcholine-induced depolarization, were enhanced by physostigmine (10 microM; n = 2) and blocked by dihydro ...

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-

Ghrelin Potentiates Miniature Excitatory Postsynaptic Currents in Supraoptic Magnocellular Neurones
Journal of Neuroendocrinology, 2009Ghrelin 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

Anoxic depression of excitatory and inhibitory postsynaptic potentials in rat neocortical slices
Journal of Neurophysiology, 19931. 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 ...

Adenosine inhibits the NMDA receptor-mediated excitatory postsynaptic potential in the hippocampus
Brain Research, 1993The 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.

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 ...

Properties of the slow excitatory postsynaptic potential in mammalian sympathetic ganglion cells
Neurophysiology, 1982Slow EPSPs evoked in the neurons of the rabbit isolated superior cervical ganglion were studied using intracellular microelectrodes. Two types of EPSPs occurring in different neurons were found. The type I slow EPSPs showed an increase during hyperpolarization of the membrane and a decrease during its depolarization.

THE GENERATION OF IMPULSES BY THE EXCITATORY POSTSYNAPTIC POTENTIAL AND THE ENDPLATE POTENTIAL
1964Publisher Summary This chapter describes impulse generation by a single synchronous bombardment before treating the more complex phenomena resulting from repetitive synaptic activation. When the spike potentials generated by an excitatory postsynaptic potential (EPSP) are recorded at sufficient speed, they are seen to have an inflexion on the rising ...
