*All activations are effects observed in whole-brain analyses corrected for multiple comparisons (significant at p < 0.05) except **p< 0.001, uncorrected for multiple comparisons. BA, Brodmann's area; L, left; R, right.

^a,b,c,d,eThe BOLD response was significantly greater to ^aRewRew than PunPun trials, ^bRewRew than RewPun trials, ^cRewPun than PunPun trials, ^dPunPun than RewRew trials, ^ePunPun than RewPun trials.
