SUMMARY Biochemical or pharmacological mechanisms which promote arrest of seizure activity are discussed in relation to two general neurophysiological processes: excessive depolarization with failure of spike generation; or, alternatively, relative hyper‐polarization with membrane stabilization. Several possible mechanisms may be envisaged: metabolic “failure”; an analogy to spreading cortical depression; membrane hydration with associated spatial and conformational changes; agents which function as membrane “labilizers” and “stabilizers”; and action of inhibitory transmitters. Reasons for favoring mechanisms which are intimately correlated with the physico‐chemical state and behavior of the neural conducting membrane are presented. RÉASUMÉA Les meAcanismes biochimiques et pharmacologiques qui preAsident aG l'arreCt de l'activiteA critique eApileptique sont discuteAs en fonction de deux processus neurophysiologiques geAneAraux: une deApolarisation excessive avec deAfaut de production de pointes; ou, alternativement, une hyperpolarisation relative avec stabilisation de la membrane. Plusieurs meAcanismes possibles sont envisageAs: insuffisance meAtabolique; pheAnomeGne analogue aG la “spreading cortical depression”; hydratation de la membrane avec modifications associeAes; agents jouant le roCle de “stabilisateur” ou de “labilisateur” de la membrane; substances inhibant la transmission. Les auteurs exposent les raisons qui leur font preAfeArer les meAcanismes qui sont intimement associeAs aG l'eAtat physicochimique et au comportement de la membrane de conduction nerveuse.
