The amplitude information of low-frequency oscillations was found meaningful in investigating the regional spontaneous neuronal activity. The amplitude of spectral component in different frequency bands exhibited distinct spatial features. We used fractional amplitude of low-frequency fluctuation (fALFF) to investigate the oscillation abnormality in idiopathic generalized epilepsy, and further extended the analysis to the fALFF across different frequency bands.
