Inhibitory Transmission: Slow Inhibitory Postsynaptic Potential

1986
J. C. Eccles (1943) was the first to show that a slow surface positive (P) potential could be recorded, when preganglionic nerves were stimulated, from mammalian sympathetic ganglia treated with curare. This P potential was further investigated in turtle sympathetic ganglia by Laporte and Lorente de No (1950). In 1961, R. M.

Excitatory and inhibitory postsynaptic potentials in cat hypoglossal motoneurons during swallowing

Experimental Brain Research, 1988
The 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.

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 ...

Nonadrenergic inhibitory postsynaptic potentials of gastric smooth muscle cells

Neurophysiology, 1973
Single intramural stimulation of the atropinized muscle strip of the guinea pig stomach by square pulses was accompanied by the formation of inhibitory postsynaptic potentials (IPSPs) in the muscle cells and by relaxation of the strip. The mean latent period of the IPSPs was 150±15 msec, and the time for its amplitude to rise and fall was 150±15 and ...

Ionic mechanism of the inhibitory postsynaptic potential of crayfish giant motor fiber

Pfl�gers Archiv European Journal of Physiology, 1969
The ionic mechanism of the inhibitory postsynaptic potential (IPSP) was studied at the giant motor fiber of crayfishProcambarus clarki (Gerard). The reversal potential of the IPSP was −53±5 mV (mean and s.d. from 51 fibers), while the resting potential was −62±6 mV.

Lingually induced inhibitory postsynaptic potentials in hypoglossal motoneurons after axotomy

Brain Research, 1981
Inhibitory postsynaptic potentials (IPSPs) produced in axotomized hypoglossal motoneurons by stimulation of the lingual nerve were explored in cats. In the ipsilateral lingual afferent synapses, the effectiveness of inhibitory synapses for the long-lasting IPSP was diminished in axotomized hypoglossal motoneurons earlier after transection of the ...

Development of excitatory and inhibitory postsynaptic potentials in the rat neocortex.

Perspectives on developmental neurobiology, 1995
The postnatal development of synaptic potentials in the rat neocortex is characterized by the sequential appearance of functional excitatory and inhibitory synapses. Morphological and electrophysiological studies provided evidence that at early stages of development, pyramidal cells are extensively coupled to each other, presumably via gap junctions ...

Serotonin attenuates a slow inhibitory postsynaptic potential in rat hippocampal neurons

Neuroscience, 1990
Activity 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.

[Monosynaptic inhibitory postsynaptic potentials of cerebral cortex neurons].

Neirofiziologiia = Neurophysiology, 1976
The 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.
