^aSeizure Onset Zone (SOZ) corresponds to areas that initiated clinical seizures during intracranial monitoring. FC Frontal Cortex, TC Lateral Temporal Cortex, MESIAL Mesial Temporal Cortex.

^bTime-adjusted baseline IED rates averaged over all contacts with at least one IED during the task window.

^cDenotes the number of contacts remaining after the exclusion of bad channels and channels outside of co-registered grey matter regions.
