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.

A dopaminergic inhibitory postsynaptic potential mediated by an increased potassium conductance
Neuroscience, 1989Intracellular recordings from intact pituitary melanotrophs show that, in the same cell, inhibitory postsynaptic potentials resulting from either pituitary stalk stimulation or exogenous dopamine are abolished by D2 receptor antagonists, display identical conductance changes, are reversed in polarity at the same membrane potential and are sensitive to ...

Effects of intracellular potassium and sodium injections on the inhibitory postsynaptic potential
Proceedings of the Royal Society of London. Series B. Biological Sciences, 1964Two barrels of double microelectrodes have been filled with different salts so that the electrophoretic injection of Na + and K + ions could be investigated in alternating sequence on the same motoneuron in the cat spinal cord. The effects of these injections on the mechanism generating the

The pathway for the slow inhibitory postsynaptic potential in bullfrog sympathetic ganglia
Journal of Neurophysiology, 1986Intracellular and sucrose gap recording techniques were used to examine synaptically evoked potentials and the response of neurons in bullfrog paravertebral sympathetic ganglia to muscarinic agonists. These neurons were defined as either B or C cells on the basis of the conduction velocity of antidromically evoked action potentials.

Abstract PREGANGLIONIC volleys evoke in the curarized superior cervical ganglion of turtles and rabbits (1,2) a positive wave (P potential) which is followed by a late occurring negative wave (LN potential). Tetanic stimulation enhances the P potential as well as the LN potential, whereas atropine completely abolishes both of them (2,3,4).

Spontaneous inhibitory postsynaptic potentials in guinea pig neocortex and olfactory cortex neurones
Neuroscience Letters, 1985The membrane potential of olfactory cortex and neocortex neurones in vitro was recorded using conventional microelectrode techniques. During recordings with KCl- or CsCl-filled microelectrodes, spontaneous, subthreshold, transient membrane depolarizations were observed.

Inhibitory postsynaptic potentials evoked in hypoglossal motoneurons by lingual nerve stimulation
Experimental Neurology, 1982Abstract The percent magnitude of a short- and a long-lasting inhibitory postsynaptic potential (IPSP) produced in tongue retractor and protruder motoneurons by lingual nerve stimulation was studied in cats. In the retractor motoneurons, stimulation of the ipsilateral lingual nerve produced primarily the short-lasting IPSP, and the neurons had ...

1. The serotonin-containing neurons in the A1 ganglion of the lobster have been shown to act as "gain setters" in neuronal circuits that control the adoption of behaviorally relevant postures. These neurons are subject to tonic inhibition, which has been proposed as an important regulator of their activity.

[Monosynaptic inhibitory postsynaptic potentials of cerebral cortex neurons].
Neirofiziologiia = Neurophysiology, 1976The auditory cortes of cats immobilized with d-tubocurarine was stimulated by monopolar macroelectrodes (tip diameter 100 mu) or micloelectrodes (tip diameter 100--15 mu). In both cases in cortical neurons located closely to the stimulation point IPSPs were recorded with latencies ranging between 0.4--1.2 and 1.4 6.0 ms.

Serotonin attenuates a slow inhibitory postsynaptic potential in rat hippocampal neurons
Neuroscience, 1990Activity of hippocampal neurons was recorded in an in vitro slice preparation. Topical application of serotonin produced hyperpolarization, blockade of a slow afterhyperpolarization which follows a burst discharge and blockade of a slow inhibitory postsynaptic potential.
