Stretch-evoked excitatory postsynaptic potentials in motoneurons
Brain Research, 1971Abstract The profile of excitatory postsynaptic potential (EPSP) produced on triceps surae motoneurons by 5 msec duration triangular wave stretch of de-efferented medial gastrocnemius (MG) and soleus (S) muscles was observed on anesthetized, spinalized cats.

Principal component analysis of minimal excitatory postsynaptic potentials
Journal of Neuroscience Methods, 1998'Minimal' excitatory postsynaptic potentials (EPSPs) are often recorded from central neurones, specifically for quantal analysis. However the EPSPs may emerge from activation of several fibres or transmission sites so that formal quantal analysis may give false results.

Summation of excitatory postsynaptic potentials in electrically-coupled neurones
Neuroscience, 2009Dendritic electrical coupling increases the number of effective synaptic inputs onto neurones by allowing the direct spread of synaptic potentials from one neurone to another. Here we studied the summation of excitatory postsynaptic potentials (EPSPs) produced locally and arriving from the coupled neurone (transjunctional) in pairs of electrically ...

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 ...

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

Effect of glutamate receptor antagonists on excitatory postsynaptic potentials in striatum
Brain Research Bulletin, 1998Glutamate, as the main transmitter of corticostriatal pathway, has a crucial role in the regulation of the activity of striatal cells as well as in pathogenesis of some diseases characterized by striatal malfunction caused by overexcitation of neurons. In the present study, the role of ionotropic excitatory amino acid receptors was investigated in the ...

All‐or‐none Excitatory Postsynaptic Potentials in the Rat Visual Cortex
European Journal of Neuroscience, 1995AbstractIntracellular recordings were obtained from supragranular neurons in slices of the rat visual cortex. In ∼25% of the cells large (0.5–1.6 mV) excitatory postsynaptic potentials (EPSPs) of constant amplitude were observed after minimal, presumably single‐fibre stimulation.

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.

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.
