THE IONIC MECHANISM GENERATING THE INHIBITORY POSTSYNAPTIC POTENTIAL

, 1964
Publisher Summary This chapter focuses on an ionic mechanism generating the inhibitory postsynaptic potential. The inhibitory postsynaptic current is entirely accountable to increases in the movements of ions down their electrochemical gradients and to the nature of the change that the inhibitory transmitter effects in the ionic permeability of the ...

Inhibitory Postsynaptic Potentials in Grasshopper Muscle

Science, 1964
Hyperpolarizing inhibitory postsynaptic potentials have been discovered in fibers of the "jumping" muscle of the grasshopper. These potentials attenuate the depolarizing excitatory postsynaptic responses. They are enhanced during depolarization of the muscle fiber with applied current and are diminished and then reversed during hyperpolarization.

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, 1975
IT 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, 1967
L'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, 1976
Monopolar 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, 1998
Rapid 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.

Phaclofen inhibition of the slow inhibitory postsynaptic potential in hippocampal slice cultures: A possible role for the GABAB-mediated inhibitory postsynaptic potential

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 ...
