Time-Frequency Strategies for Increasing High-Frequency Oscillation Detectability in Intracerebral EEG
High-frequency oscillations (HFOs) are considered to be a good marker of the tissues which have to be removed. We investigated several methods to flatten (i.e. whiten) the spectrum to improve HFO detectability. Our method, the H0 z-score, provides an optimal framework for representing and detecting HFOs, independent of a baseline and a priori frequency bands.
