“Both the induction and maintenance of epileptiform activity was blocked by inhibiting action potential generation with tetrodotoxin or substitution of sodium with choline or by blocking AMPA/KA ionotropic glutamate receptors.”
“Depolarization above ‐40 mV activated a fast transient sodium inward current that was eliminated by substituting Na+ for choline and blocked in the presence of 1 μM TTX.”
“The inward current was transient, eliminated by substitution of choline for Na+ in the bathing solution, and reduced by 50% in the presence of 1 μM tetrodotoxin.”

“Addition of tetrodotoxin or replacement of the Cl- ions by OAc- ions or of the Na+ ions by choline ions reduced the depolarizing afterpotential and the action potential.”
