Correlation analysis between the post-treatment and pretreatment subjective pain rating changes and fMRI signal changes on placebo and control sides

Correlation	Area (Brodmann area)	Z score	r score of peak voxel	Number of voxels in cluster	Peak coordinate (x, y, z)
Negative	Left inferior frontal gyrus (47)	3.69	-0.80	52	-22, 12, -20
	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.
