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 ...

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.

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.

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.

Kisspeptin-10 potentiates miniature excitatory postsynaptic currents in the rat supraoptic nucleus
Brain Research, 2014Kisspeptin 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 ...

Abstract Membrane potential dependence of excitatory postsynaptic potentials (EPSPs) produced in masseteric motoneurons by stimulation of either the infraorbital or the lingual nerve was explored in cats. No reversal of infraorbitally and lingually induced EPSPs was obtained even when the membrane was depolarized with large depolarizing currents.

Short-term heterosynaptic potentiation of cholinergic excitatory postsynaptic currents and potentials in defensive behavior command neurons was found to be evoked by stimulation of the visceral sac in the common snail. It is suggested that a mechanism increasing the choline resistance of the postsynaptic zones of command neuron membranes is involved in

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

Depression of monosynaptic excitatory postsynaptic potentials by Mn2+ and Co2+ in cat spinal cord
Neuroscience, 1979Abstract In cats anesthetized with allobarbitone-urethane, Mn 2+ and Co 2+ (and occasionally La 3+ ) were released extracellularly from micropipettes while recordings were made of monosynaptic excitatory postsynaptic potentials evoked in lumbosacral motoneurones by Ia afferent stimulation.
