Summary: This report examines several concepts concerning the latent period to the first convulsive seizure, subsequent increases in seizure frequency, and possible mechanisms of epileptogenesis after kainate‐induced status epilepticus. Previous data concerning the latent period and seizure progression from intermittent and continuous behavioral monitoring are compared, and hypothetical mechanisms of acquired epilepsy are discussed. Data involving electrographic recordings with tethered animals or with radiotelemetry are assessed in terms of their potential for addressing different hypotheses concerning the latent period and progressive changes in seizure frequency. Experimental analyses of the time course of occurrence of spontaneous seizures are interpreted in terms of possible cellular mechanisms underlying epileptogenesis.
