Medication being taken before scan/medication at time of scan (see Methods).
EEG at time of recruitment obtained from patient clinical EEG records. Similar EEG recordings were obtained for each patient during EEG-fMRI.
Scans were repeated on different days for some patients. Several (up to 4) data runs were performed on each day.
Total number of seizures across all scans and runs.
