Tetanus-induced potentiation of inhibitory postsynaptic potentials in hippooampal CA1 neurons
Canadian Journal of Physiology and Pharmacology, 1995In the present study, tetanus-induced potentiation of inhibitory postsynaptic potentials (IPSPs), previously described by our laboratory, was further investigated in guinea pig hippocampal CA1 neurons. Tetanic stimulation of the stratum radiatum induced a long-term potentiation of the excitatory postsynaptic potential and a potentiation of the γ ...

Dendritic amplification of inhibitory postsynaptic potentials in a model Purkinje cell
European Journal of Neuroscience, 2006AbstractIn neurons with large dendritic arbors, the postsynaptic potentials interact in a complex manner with active and passive membrane properties, causing not easily predictable transformations during the propagation from synapse to soma. Previous theoretical and experimental studies in both cerebellar Purkinje cells and neocortical pyramidal ...

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.

Valproate enhances inhibitory postsynaptic potentials in hippocampal neurons in vitro
Brain Research, 1987Effects of sodium valproate (0.5-10 mM) on hippocampal cells (CA3 pyramidal cells and granule cells) of the guinea pig in vitro were studied by intra- and extracellular recording. Inhibitory postsynaptic potentials were markedly and reversibly augmented. Their shunting action as well as duration increased by more than 150%.

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 ...

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).

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.

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.

Ionic mechanism of the inhibitory postsynaptic potential of crayfish giant motor fiber
Pfl�gers Archiv European Journal of Physiology, 1969The 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.

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 ...
