A Mixed L2 Norm Regularized HRF Estimation Method for Rapid Event-Related fMRI Experiments
Figure 4
Inspection of the HRF estimates of the different methods. The lines in different colors represent the different HRF estimates of the voxels. The -axis indicates the time relative to the event onset (TR = 2 s), and the -axis indicates the BOLD signal. Each HRF estimate was normalized by dividing it by its maximum value.
