Comparison between BH and PDB protocols: Example of BOLD signal time courses averaged across trials and across regions that display significant signal responses (left, error bars represent standard deviation across trials), and corresponding CVR maps (in normalized units of BOLD percent signal change per mmHg (%/mmHg), right), for one illustrative subject. The BOLD signal changes in response to the different tasks can be seen clearly, with a signal increase/decrease for BH/PDB, respectively. A Fourier basis modeling approach was used to obtain the CVR maps (Pinto et al., 2016).
