Hemodynamic Scaling of fMRI-BOLD signal: Validation of low frequency spectral amplitude as a Scalability Factor

fMRI-BOLD signal representing neural activity may be optimized by discriminating MR signal components related to neural activity and those related to intrinsic properties of the cortical vasculature. The objective of this study was to diminish the hemodynamic change independent of neural activity to...
