Short Content: 1 introduction Epilepsy's diagnosis main dependence clinical medical history, the electroencephalogram inspection may take one extremely valuable auxiliary diagnosis method. Statistics indicated that 80% about epilepsy patients have the definite brain electricity to be unusual, but has 5~20% about epilepsy patient electroencephalogram performance to be normal. Especially to the clinical diagnosis difficult non-typical epileptic paroxysm, each kind of heterogeneous epilepsy and concealment epilepsy, the electroencephalogram inspection's importance is more prominent, even is playing decisive role [1]. Brain electricity (EEG) ...
