Inhibitory postsynaptic potentials of hypoglossal motoneurons of the cat

open access: closedExperimental Neurology, 1972
Abstract The hypoglossal nerve of the cat contains some afferent fibers, but the role of these afferents in controlling hypoglossal motoneuron activity has not yet been analyzed. The effect of hypoglossal nerve stimulation on activity of hypoglossal motoneurons was investigated using microelectrode technique.

THE IONIC MECHANISM GENERATING THE INHIBITORY POSTSYNAPTIC POTENTIAL

open access: closed, 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]

open access: possibleProceedings 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 ...
