case_images: Clinical EEG data and previous cryogenic MEG data. Top: 10-s EEG signal (longitudinal bipolar montage) recorded during the clinical follow-up 7 months before the multimodal OPM acquisition, band-pass filtered at 0.53-70 Hz. Middle: Non-simultaneous 10 s of cryogenic MEG signals (magnetometers) recorded 7 months before the multimodal acquisition, band-pass filtered at 3-40 Hz. Bottom: Axial brain T1-weighted MRI illustrating the resection cavity after the resection of a right temporal dysembryoplastic neuroepithelial tumor (Left). Source localization of IEDs detected with cryogenic MEG signals (for methods, see) displayed on parasagittal (Middle left; right hemisphere), coronal (Middle right), and axial (Right) sections.

case_images: She underwent a right anterior temporal lobectomy leading to seizure-freedom (Engel class 1A) but IEDs remain very frequent with a maximal amplitude over C4-T4 electrodes (Figure 1). She underwent cryogenic MEG 7 months prior to OPM-MEG recording, which showed right centrotemporal IEDs (Figure 1).
