Brain regions identified by analysis of target trials

Brain Region		Side	Center of Mass (mm) X, Y, Z	Brodmann Area(s)	Volume (μl)
1	Superior temporal gyrus, temporoparietal junction	L	-54.5, -29, 12.1	41, 42	539
2	Superior temporal gyrus, temporoparietal junction	R	53.5, -27.2, 16.5	40, 41	300
3 & 8	Anterior insula & precentral gyrus	R	36.7, 3.2, 17.6	13 & 6	808
4 & 9	Posterior insula & precentral gyrus	R	46.5, -5.5, 6.3	13 & 6	582
5	Fusiform gyrus, into parahippocampal gyrus	L	-23.5, -45.4, -9.3	19, 37	680
6	Fusiform gyrus	R	24.1, -53, -9.3	19, 37	741
7	Precentral gyrus	R	26.3, -13.4, 65.1	6	240
10	Midcingular gyrus	B	-3.3, -7.9, 42	24	318
11	Occipital cortex: lingual gyrus, cuneus	B	1.5, -78.5, 1.5	17, 18	9625
12	Middle occipital gyrus	L	-31.4, -88.1, 0.7	18	907
13	Middle occipital gyrus	R	28.8, -88.6, 0.7	18	1110

Regions in Talairach space where the BOLD signal intensity varied linearly with the number of cued locations. All ROIs except the middle occipital gyri increased in activation with less precise spatial cueing, an effect that was dependent upon the presentation of a target signal. L = left, R = right, B = bilateral. Regions 3 and 8 as well as regions 4 and 9 were artificially separated by removing one and two voxels of functional data, respectively.
