Slope of the power spectral density flattens at low frequencies (<150 Hz) with healthy aging but also steepens at higher frequency (>200 Hz) in human electroencephalogram
The power spectral density (PSD) of the brain signals is characterized by two distinct features: oscillations, which are represented as distinct “bumps,” and broadband aperiodic activity, that reduces in power with increasing frequency and is characterized by the slope of the power falloff. Recent s...
