Three regression factors for the task in the study. Three independent boxcar-shaped regression factors were set up. These three sequences represent the regression factors for (A) all trials (including AX, AY, BX, BY), (B) AY trials and (C) BX trials. The three sequences were convolved with statistical parametric mapping’s (SPM’s) hemodynamic response function (HRF) to form the final task sequence.
