1 After the seizure has been viewed using conventional frequencies and muscle activity has been removed, a search for baseline shifts should be performed by opening the high-pass filter to at least 0.1 or 0.01 Hz. When intracranial recordings are performed the conventional frequency band, DC shifts and HFOs should be evaluated separately for seizure onset determination. HFOs can be ascertained by setting the high-pass filter at >60 Hz and leaving the low-pass filter open.292 Source: Focal Epilepsy, Atlas of Pediatric EEG Citation: Laoprasert P.
