Location and extent of functional clusters showing a difference in PPI with vmPFC between social and nonsocial PUN decisions that was greater than or equal to the effect in our a priori TPJ region

Region	Hemisphere	Extent	x	y	z	Peak T
TPJ	R	144	60	−48	16	3.97
Parahippocampal gyrus	R	93	22	−26	−14	3.87
Lingual gyrus	R	86	28	−50	4	3.87
Fusiform cortex	L	78	−34	−38	−18	4.12
Fusiform cortex	L	66	−38	−2	−32	4.31
White matter/insular cortex	L	60	−28	−16	24	3.96
STG	L	51	−52	−24	6	3.36

Peak coordinates (x,y,z) are listed in MNI space. T values are test statistics derived from 5000 permutations of the data. Clusters reported are all of those that surpass a threshold set by lowest t value in the small volume corrected TPJ cluster (t > 2.29) and minimum cluster size of 50 voxels (2 × 2 × 2 mm). Note that these results are reported here for completeness only and are not corrected for multiple comparisons and thus not the subject of any inference in this paper. STG, Superior temporal gyrus.
