Glutamate mediates an inhibitory postsynaptic potential in dopamine neurons
Nature, 1998Rapid information transfer within the brain depends on chemical signalling between neurons that is mediated primarily by glutamate and GABA (gamma-aminobutyric acid), acting at ionotropic receptors to cause excitatory or inhibitory postsynaptic potentials (EPSPs or IPSPs), respectively.

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 ...

Monosynaptic inhibitory postsynaptic potentials of cortical neurons
Neurophysiology, 1976Monopolar intracortical stimulation of the auditory cortex was carried out in cats immobilized with D-tubocurarine. A macroelectrode (tip diameter 100 µ) or a microelectrode (tip diameter 10–15 µ) was used for stimulation. In both cases, besides excitatory responses, primary IPSPs with latent periods of 0.4–1.2 and 1.4–6.0 msec were recorded in ...

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.

Effects of intracellular potassium and sodium injections on the inhibitory postsynaptic potential
Proceedings of the Royal Society of London. Series B. Biological Sciences, 1964Abstract Two 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.

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 ...

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).

Journal of Neurophysiology, 1993
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.

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 ...

Inhibitory modulation of long-term potentiation: Evidence for a postsynaptic locus of control
Brain Research, 1982Long-term potentiation (LTP) of the excitatory synapses of the perforant path onto the granule cells of the fascia dentata was prevented, or greatly reduced in amount, by stimulation of the contralateral hilus, a source of the commissural afferents and an indirect source of granule cell inhibition.
