Effects of intracellular potassium and sodium injections on the inhibitory postsynaptic potential [PDF]
Proceedings of the Royal Society of London. Series B. Biological Sciences, 1964 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. The effects of these injections on the mechanism generating the

Prolongation of hippocampal inhibitory postsynaptic potentials by barbiturates
Nature, 1975IT is well documented that barbiturates dramatically prolong presynaptic inhibition1–4. Their effect on postsynaptic inhibition is less clear, although the available evidence suggests that a similar enhancement may occur at some sites5–7. Since the inhibitory postsynaptic potentials (i.p.s.p.s) in hippocampal neurones are unusually large and the ...

Interneuronal barrages and ripple superposed on inhibitory postsynaptic potentials
Experientia, 1967L'activite electrique des neurones du noyau thalamique ventro-lateral est etudiee ici chez des chats anesthesies au nembutal et immobilises avec du flaxedil au moyen d'un enregistrement intracellulaire. Nous avons observe que l'enregistrement de certains neurones montre que le potentiel nomme inhibiteur postsynaptique (IPSP) est accompagne de la ...

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 ...

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.

Neuroscience, 1990
The GABAA antagonist bicuculline methiodide and the GABAB antagonist phaclofen were used to examine the function of the fast inhibitory postsynaptic potential and slow inhibitory postsynaptic potential, in hippocampal slice cultures in the rat. These cultures form easily-visualized monolayers of nerve cells which maintain the structure and synaptic ...

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.
