High Frequency Oscillations and spikes: Separating real HFOs from false oscillations

High Frequency Oscillations and spikes: Separating real HFOs from false oscillations

Highlights • We studied simultaneous sharp events and High Frequency Oscillations (HFOs, 80–500 Hz) in intracranial EEG. • We developed a method to separate real oscillations from those generated by the filtering of sharp transients using detection of oscillations on the original signal. • Time–freq...

Zusammenfassung:Highlights • We studied simultaneous sharp events and High Frequency Oscillations (HFOs, 80–500 Hz) in intracranial EEG. • We developed a method to separate real oscillations from those generated by the filtering of sharp transients using detection of oscillations on the original signal. • Time–frequency representation may mask real HFOs concurrent with broadband activities.
