| 1 | Advances of Intracranial Electroencephalography in Localizing the Epileptogenic Zone显示文摘Intracranial electroencephalography(i EEG)provides the best precision in estimating the location and boundary of an epileptogenic zone. Analysis of i EEG in the routine EEG frequency range(0.5–70 Hz) remains the basis in clinical practice. Low-voltage fast activity is the most commonly reported ictal onset pattern in neocortical epilepsy, and low-frequency high-amplitude repetitive spiking is the most commonly reported ictal onset pattern in mesial temporal lobe epilepsy. Recent studies using wideband EEG recording have demonstrated that examining higher(80–1000 Hz) and lower(0.016–0.5 Hz) EEG frequencies can provide additional diagnostic information and help to improve the surgical outcome. In addition,novel computational techniques of i EEG signal analysis have provided new insights into the epileptic network.Here, we review some of these recent advances. Although these sophisticated and advanced techniques of i EEG analysis show promise in localizing the epileptogenic zone,their utility needs to be further validated in larger studies. | Bo Jin Norman K.So Shuang Wang | 2016 | Neuroscience Bulletin2016，32，5： | 9 |
