Demonstration of marked events and the hemodynamic response maps for IED type 1 of patient 1.

a) One example of IED template marked outside of scanner shown on average montage (left) and bipolar montage (right). The IED contains spikes with maximum at T3 and F9-T9. b) Top 6 candidate events proposed by our method for EEG inside scanner (Top: average montage, bottom: bipolar montage; Note that the candidate events provide by our method contain periods of varying length). Red lines show the positions of IEDs from the ground truth (GT) results, while black lines show the positions of IEDs from the edited results. The events were classified into different situations by marking the outlines with different colors, Green: IEDs from edited results missed in GT-results, Red: IEDs from both GT and edited results, yellow: No IED is found from either results. c) Corresponding hemodynamic response maps from ground truth manual markers (top) and edited makers (bottom). The primary cluster of edited result is concordant with SEEG-defined SOZ, while we cannot find such concordance from hemodynamic response map of GT results.
