Table 2. Brain regions exhibiting significantly decreased blood oxygen level-dependent (BOLD) signal during attention to heartbeat sensations relative to exteroceptive sensations in suicide attempters relative to non-attempters.

Location	MNI Coordinates			Peak t	Volume (mm3)
	x	y	z
Right Dorsal Posterior Insula	31	−19	15	−3.7	469
Right Dorsal Mid-Insula	39	-1	13	−3.4	352
Right Precuneus and Posterior Cingulate	5	−61	27	−4.8	1568
Right Superior Temporal Gyrus	65	−29	5	−5.2	784
Right Middle Cingulate Cortex	11	-7	45	−5.0	712
Right Superior Medial Gyrus	1	57	17	−5.2	544

Note: A voxel-wise threshold of p < 0.005 was set for the insula, and a voxel-wise threshold of p < 0.0005 for the rest of the brain; all significant activations passed a cluster-size correction for multiple comparisons of α < . 05.
