Amplitude of Low-Frequency Fluctuation
Amplitude of Low-Frequency Fluctuation (ALFF) is a resting-state fMRI metric that quantifies the strength of spontaneous low-frequency oscillations (typically 0.01–0.1 Hz) in the brain. Introduced by Yang and colleagues in 2007, ALFF provides a voxel-wise measure of local brain activity, reflecting the amplitude of spontaneous fluctuations in blood oxygen levels at rest.
