Rodent Model of Disease afterdischarges model true The single-evoked epileptic afterdischarges model (AD) is another important approach to electrical stimulation. It is induced in specific brain regions, resembling complex partial seizures if applied into limbic structures and myoclonic seizures if applied into the sensorimotor cortex. AD is useful for investigating electrophysiological and behavioral correlates of focally generated seizure-like patterns that often spread to nonstimulated networks
