Results of random effects analysis for brain responses during baseline activation compared with prosocial decisions in dictator game. Displayed are activations surviving peak level correction at P < 0.05, FWE corrected (threshold of P < 0.005 used to define the clusters, small volume correction (SVC, spheres of 10 mm radius) (L = left hemisphere, R = right hemisphere; in brackets: P < 0.001, uncorrected)
