These measures were demonstrated to be stable over a short-term period of 3 consecutive days with the same DLS. Between ImCoh FC differences between EZs and non-EZs were reduced with DLS decreases, whereas other measures were not affected by DLS. FC differences between EZs and non-EZs were seen during both resting-state and pseudo-rest conditions; ImCoh values were strongly correlated between the 2 conditions, whereas PDC values were not.Discussion Inward and nondirected SEEG FC is higher in presumed EZs vs non-EZs and measures are stable over time. However, certain measures may be affected by ASM dose, as between ImCoh differences between EZs and non-EZs are less pronounced with lower doses, and other measures such as PDC are poorly correlated across recording conditions. These findings allow novel insight into how SEEG FC measures may aid surgical localization and how they are influenced by ASMs and other factors.ASM=antiseizure medication; DLS=drug load score; EMR=electronic medical record; EMU=epilepsy monitoring unit; EZ=epileptogenic zone; FC=functional connectivity; FDR=false discovery rate; iEEG=intracranial EEG; ImCoh=imaginary coherence; IRB=institutional review board; LME=linear mixed effects; MEG=magnetoencephalography; PDC=partial directed coherence; RNS=responsive neurostimulation; SEEG=stereo-EEG; VUMC=Vanderbilt University Medical Center ER -
