CHB-MIT

The CHB-MIT Scalp EEG Database is a collection of continuous EEG recordings from 24 pediatric subjects with intractable epilepsy, acquired at Children's Hospital Boston. The dataset comprises 686 EEG scans containing 198 annotated seizure events, recorded at 256 Hz using the International 10-20 electrode system with bipolar montages. Subjects (5 males and 18 females, ages 1.5-22 years) were monitored for several days following anti-seizure medication withdrawal to characterize seizure patterns and assess surgical intervention candidacy. The original EEG data in .edf format from PhysioNet has been converted to BIDS format with standardized channel naming and preserved non-EEG channels. Note: Surrogate dates were used to replace protected health information, which may result in inaccurate age calculations in automated reports.
