A Mixed L2 Norm Regularized HRF Estimation Method for Rapid Event-Related fMRI Experiments

Table 1

Mean number of voxels across all subjects used in different methods. Unselected voxels were all located in OR areas or early visual areas. Voxels were selected from the unselected voxel set based on the selection criterion. Object responsive (OR) voxels were strongly activated in localizer runs ( -test, , familywise error corrected). Retinovoxels were located in the early visual area, which was delineated via retinotopic mapping analysis.
