Significant activation clusters associated with the perception of fairness and unfairness

Brain region	Hemisphere	x	y	z	No. of voxels	Z

—VMPFC	R	10	53	−10	355	6.04
—Posterior insula	L	−53	−24	22	468	6.65
—Posterior insula	R	52	4	4	96	6.34
—Posterior cingulate	L	−11	−24	46	145	6.65
—Superior temporal sulcus	L	−60	−20	−10	96	5.99
