Right inferior frontal gyrus (44) 3.15 -0.72 20 28, 48, 2
Left inferior frontal cortex (46) 3.06 -0.71 41 -48, 40, 6
Right middle frontal gyrus (6) 3.01 -0.70 21 26, 0, 48
Bilateral rACC (24) 2.82 -0.67 22 10, 36, -2
Right fusiform gyrus (37) 2.83 -0.68 27 -50, -48, -20
Right parahippocampus 3.49 -0.78 40 12, -32, -4
Left cerebellum 3.38 -0.75 25 -32, -72, 30
Right cerebellum 2.88 -0.67 26 36, -60, -44
Right pons 3.70 -0.80 64 10, -32, -26
Positive Nothing above threshold
  • The threshold is set to p < 0.005 with 20 continuous voxels. Peak coordinates refer to the MNI atlas.
