Between-group differences in activation during the n-back task (p < 0.05, FWE-corrected)

BOLD activation between-group contrasts; region	Peak MNI x coordinate (mm)	Y coordinate	Z coordinate	Cluster size (voxels)	Z score
PBI > Controls
Right perisylvian cortex	45	−17	0	3125	3.81
Left perisylvian cortex	−58	−3	2	2468	3.88
Controls > PBI
Right parietal cortex	38	−63	57	10,762	6.71
Left parietal cortex	−23	−68	59	9024	6.13
Left dorsal prefrontal	−29	8	60	8617	5.56
Right dorsal prefrontal	33	7	60	4457	6.02
Right cerebellum	15	−79	−22	3414	4.35
Left ventrolateral prefrontal	−38	54	21	2807	4.27
Left cerebellum	−46	−71	27	2456	4.24
VPT-N > PBI
Bilateral cerebellum	−7	−83	−16	4681	4.42
Right parietal cortex	49	−50	55	4481	3.88
Left parietal cortex	−39	−62	57	3187	4.43

Note that analysis was carried out in the space of the study-specific template. Results were mapped from the custom template into MNI space in order to allow for co-ordinates to be reported. There were no significant clusters in the PBI > VPT-N, Controls > VPT-N, and VPT-N > Controls contrasts.
