Comparison between BH and rs-fMRI protocols: (Top) CVR amplitude and delay maps obtained using BH BOLD-fMRI and the Fourier basis modeling approach (Pinto et al., 2016). (Bottom) Maps of ALFF and fALFF computed in the 0.01 - 0.023 Hz frequency band. All maps are group averages across 12 healthy individuals. For comparison purposes with the rs-fMRI metrics, the CVR amplitude maps are represented in non-normalized units of absolute BOLD percent signal change (PSC).
