Fig. 1From: Beta to theta power ratio in EEG periodic components as a potential biomarker in mild cognitive impairment and Alzheimer’s dementiaWhole-brain averaged relative power spectral density curves for full power spectrum and periodic components (rhythmic oscillations) in addition to fractal background components (aperiodic part or 1/f-like noise in log-log spacing) in Healthy Control (HC) (red), Mild Cognitive Impairment (MCI) (blue), and Alzheimer’s dementia (AD) (black) participants. In the full power and periodic components panels error bars represent standard errorsBack to article page
