EEG aperiodic and alpha spectral parameters

Age is associated with EEG aperiodic and alpha spectral parameters in humans (Nonlinear inverted U-shaped lifespan trajectory).

“For both processes, the spectral parameters follow a nonlinear inverted U-shape lifespan trajectory.”

Lifespan development of EEG alpha and aperiodic component sources is shaped by the connectome and axonal delays
