| Sažetak≠ | 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. | Dynamic Functional Connectivity (dFC) is an analytical framework that tracks changes in functional connectivity between brain regions over time, rather than averaging connectivity across an entire scanning session. Systematized by Hutchison and colleagues in 2013, dFC reveals how brain networks reorganize moment-to-moment, providing insights into transient brain states and cognitive flexibility. |
