Whole-brain correlates of intensity and pleasantness

	Hemisphere	Peak x, y, z	Peak Z	Number of voxels	p-value
Intensity: positive correlates (all regions significant in intensity > pleasantness; see Table 2)
Primary somatosensory cortex	R	32, −32, 72	5.22	1062	p < 0.00001
Secondary somatosensory cortex/posterior insula	R	46, −26, 20	6.52	745	p < 0.00001
	L	−50, −22, 16	5.54	460	p < 0.00001
Intensity: negative correlates (not significant in contrast)
Angular gyrus	R	26, −42, 40	−5.57	2474	p < 0.00001
Supramarginal gyrus	L	−22, −58, 40	−4.44	277	p = 0.0002
Occipital cortex	L	−24, −62, −6	−4.42	471	p < 0.00001
	L	−22, −74, 18	−4.25	212	p = 0.002
	L	−48, −50, 22	−3.77	184	p = 0.004
Pleasantness: positive correlates (all regions significant in pleasantness > intensity; see Table 2)
Anterior cingulate cortex	L	−8, 38, 4	4.46	196	p = 0.003
Pleasantness: negative correlates (not significant in contrast)
Occipital cortex	R	28, −86, 34	−5.09	300	p = 0.0001

Clusters above a threshold of Z > 3 are displayed with whole-brain correction for multiple comparisons (p < 0.01; n = 26). x, y, and z refer to the MNI coordinates corresponding to the left–right, anterior–posterior, and inferior–superior axes, respectively; Z refers to the highest Z-score within a cluster. A positive Z-value indicates a positive correlation between the subject's ratings and the BOLD response.
