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.

Topography of recurrent inhibitory postsynaptic potentials between individual motoneurons in the cat
Journal of Neurophysiology, 19941. The amplitude of recurrent inhibitory postsynaptic potentials (RIPSPs) was examined in pairs of lumbosacral motoneurons that were separated by a known distance and were identified by antidromic stimulation of muscle nerves. One motoneuron was stimulated by injecting depolarizing current pulses, and postsynaptic responses were recorded and averaged ...

Anoxic depression of excitatory and inhibitory postsynaptic potentials in rat neocortical slices
Journal of Neurophysiology, 19931. 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 ...

The suppression of lingually or cortically induced postsynaptic potentials produced by conditioning stimulation of the cerebral cortex or the lingual nerve was studied in cat hypoglossal motoneurons. We have demonstrated that lingually or cortically induced inhibitory postsynaptic potentials were effectively suppressed by a conditioning stimulus of the

The inhibitory response evoked in presumably serotonergic dorsal raphe neurons by stimulation of the lateral habenular nucleus was examined in the rat using intracellular recording techniques. Electrical stimulation of the lateral habenula produces a long-lasting hyperpolarization in dorsal raphe neurons having the slow spontaneous firing pattern (0.5 ...

Pertussis toxin blocks a late inhibitory postsynaptic potential in hippocampal CA3 neurons
Neuroscience Letters, 1987These experiments show that a synaptic response, namely the late inhibitory postsynaptic potential (IPSP) of hippocampal CA3 neurons of rats, is blocked by pertussis toxin, an inactivator of several GTP-binding proteins (G-proteins) excluding the G-protein that stimulates adenylyl cyclase. This blockage occurred without a similar effect upon either the
