Recent research has unveiled the aperiodic component of neural power spectra as a promising non-invasive biomarker for the balance between excitatory and inhibitory neural processes (E-I balance), assessable through electroencephalography (EEG) and magnetoencephalography (MEG). Through simulations and in vivo local field potential assessments, it has been demonstrated that a reduced slope of the aperiodic component indicates an excitatory state, whereas an increased slope suggests an inhibitory state. Nonetheless, the effectiveness of the aperiodic slope as a marker for E-I balance in somatose
