Variance analysis of excitatory postsynaptic potentials in cat spinal motoneurons during posttetanic potentiation

Journal of Neurophysiology, 1989
1. Fluctuations in the peak amplitudes of composite excitatory postsynaptic potentials (EPSPs) in cat spinal motoneurons were analyzed during posttetanic potentiation (PTP). Each of a series of identical tetanic stimulus trains delivered to a muscle nerve was followed by 45 test stimuli applied at 2-s intervals.

Somatostatin regulates excitatory amino acid Letterreceptor-mediated fast excitatory postsynaptic potential components in vagal motoneurons

Neuroscience, 1993
Somatostatin is considered to be a brain neurotransmitter/neuromodulator; however, there is little concrete information on how this peptide contributes to generation of synaptic potentials in the mammalian central nervous tissue. Recently, a well-defined somatostatin-containing pathway has been traced from the subnucleus centralis of the solitarial ...

Excitatory Postsynaptic Potentials Trigger a Plateau Potential in Rat Subthalamic Neurons at Hyperpolarized States

Journal of Neurophysiology, 2001
The subthalamic nucleus (STN) directly innervates the output structures of the basal ganglia, playing a key role in basal ganglia function. It is therefore important to understand the regulatory mechanisms for the activity of STN neurons. In the present study, we aimed to investigate how the intrinsic membrane properties of STN neurons interact with ...

Potentiation of excitatory postsynaptic potentials during and after repetitive stimulation in thin hippocampal sections

Experimental Brain Research, 1980
Excitatory postsynaptic potentials (EPSPs) elicited by mossy fiber stimulation were recorded intracellularly from neurons in the CA3 region in thin hippocampal sections in vitro and potentiation of the EPSPs was examined during and after repetitive stimulation.

A rise in postsynaptic Ca 2+ potentiates miniature excitatory postsynaptic currents and AMPA responses in hippocampal neurons

Neuron, 1994
We have investigated the site of expression of the potentiation of excitatory postsynaptic currents (EPSCs) induced by the activation of postsynaptic voltage-sensitive Ca2+ channels, by examining the effect of depolarizing pulses on miniature (m) EPSCs and responses to AMPA.

Kisspeptin-10 potentiates miniature excitatory postsynaptic currents in the rat supraoptic nucleus

Brain Research, 2014
Kisspeptin is the natural ligand of the G protein-coupled receptor -54 and plays a major role in gonadotropin-releasing hormone secretion in the hypothalamus. Kisspeptin-10 is an endogenous derivative of kisspeptin and has 10 -amino acids. Previous studies have demonstrated that central administration of kisspeptin-10 stimulates the secretion of ...

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 ...

Fast hyperpolarization following an excitatory postsynaptic potential in cat bladder parasympathetic neurons

Neuroscience, 1989
Intracellular recording techniques were used to study a fast hyperpolarizing potential following the fast excitatory postsynaptic potential evoked by an orthodromic nerve stimulation in cat bladder parasympathetic ganglion cells. In the 61 ganglion cells examined, two types of responses were recorded on stimulating the preganglionic nerve; one had only

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 ...
