Local Sleep Slow-Wave Activity Colocalizes With the Ictal Symptomatogenic Zone in a Patient With Reflex Epilepsy: A High-Density EEG Study by Eric W. Moffet, Eric W. Moffet, Ruben Verhagen, Ruben Verhagen, Ruben Verhagen, Benjamin Jones, Benjamin Jones, Graham Findlay, Graham Findlay, Elsa Juan, Elsa Juan, Elsa Juan, Tom Bugnon, Tom Bugnon, Armand Mensen, Mariel Kalkach Aparicio, Rama Maganti, Aaron F. Struck, Giulio Tononi, Melanie Boly, Melanie Boly

“…We assessed for statistical differences in maximum SWA between the patient and controls within REM sleep, NREM sleep, wakefulness, and seizure. Then, we completed an identical statistical comparison after first subtracting intrasubject REM sleep SWA from that of NREM sleep, wakefulness, and seizure SWA.Results: The topographical analysis revealed greater left hemispheric SWA in the patient vs. controls in all vigilance states except REM sleep (which showed a right hemispheric maximum). …”
