About: Amplitude of low frequency fluctuations

An Entity of Type: software, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Amplitude of Low Frequency Fluctuations (ALFF) and fractional Amplitude of Low Frequency Fluctuations (f/ALFF) are neuroimaging methods used to measure spontaneous fluctuations in BOLD-fMRI signal intensity for a given region in the resting brain. Electrophysiological studies suggest that low-frequency oscillations arise from spontaneous neuronal activity. Though ALFFs have been researched extensively in fMRI based theoretical models of brain function, their actual significance is still unknown.
