Application of 256-channel dense array electroencephalographic source imaging in presurgical workup of temporal lobe epilepsy

Highlights • 256-channel dense array electroencephalographic source imaging (dESI) showed the best sensitivity (>90%) and specificity (75%) with comparison to conventional tools. • Analysis of the relationship between the 256-channel dESI source patterns and surgical outcome showed that cases wit...

Description
Summary:Highlights • 256-channel dense array electroencephalographic source imaging (dESI) showed the best sensitivity (>90%) and specificity (75%) with comparison to conventional tools. • Analysis of the relationship between the 256-channel dESI source patterns and surgical outcome showed that cases with “single source” had better prognosis than with “multiple sources.” • The resection of dESI sources representative of the irritative zone is related to good surgical prognosis in temporal lobe epilepsy (TLE).
