Features and Futures: Seizure Detection in Partial Epilepsies

Many factors underlying basic epileptic conditions determine the characteristics of epileptic seizures and the therapeutic outcome. Diagnosis and treatment rely on the clinical manifestations as well as electroencephalographic (EEG) epileptic activities. This article briefly reviews the fundamentals of the EEG, interictal, and ictal electrical activities of both extracranial and intracranial EEG of partial epilepsies, based on the information obtained from epilepsy patients who have undergone epilepsy surgery. The authors also present the status of their current research, focusing on decomposed seizure sources and the rendered spatial-temporal transitions in focal seizure.
