List of brain regions revealed by between-group contrasts during humor comprehension process and with comprehensibility and funniness ratings analyzed as parametric modulators (*). Statistical analysis utilized a non-parametric whole-brain voxel-wise Pseudo-t-test. Localizations are reported as local maximum threshold with k ≥ 10 voxels extent threshold and with False Discovery Rate (FDR) correction at alpha = 0.0500, or uncorrected at alpha = 0.0010. L – left hemisphere; R – right hemisphere; BA – Brodmann's area; k – number of voxels in analyzed cluster size; MNI - Montreal Neurological Institute coordinates.
