A fitting method that attempts to separate and parameterize the aperiodic and periodic spectral components called \u201cfitting oscillations and one over f\u201d (FOOOF) was applied to a set of annotated whole-night sleep EEG recordings of 251 subjects from a wide age range (4\u201369 years). Most of the extracted parameters exhibited sleep stage sensitivity; significant main effects and interactions of sleep stage, age, sex, and brain region were found. The spectral slope (describing the steepness of the aperiodic component) showed especially large and consistent variability between sleep stages (and low variability between subjects), making it a candidate indicator of sleep states. The limitations and arisen problems of the FOOOF method are also discussed, possible solutions for some of them are suggested.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Scale-free and oscillatory spectral measures of sleep stages in humans Front.
