Cerebral regions showing significantly different power of response to the non-word rhyming task and the letter case judgment task between the very preterm group and the control group

	Number of voxels	Talairach coordinates (mm)			Maximum difference in FPQ
	Number of voxels	x	y	z	Maximum difference in FPQ
x, y, and z refer to the stereotactic coordinates³⁶ of the voxel within each cluster with the largest fundamental power quotient (FPQ, reflecting the significance of periodic change). The reference point for the coordinates is the junction of the vertical anterior commissural line and the intercommissural line. The reference plane is the bicommissural plane. x refers to millimetres left (−) and right of the reference point, y to millimetres anterior and posterior (−) to the reference point, and z to planes above and below (−) the reference plane.

Left cerebellum	6	−38	−64	−13	0.3
Very preterm group > controls
Right precentral gyrus	7	26	−22	59	0.3

Letter case judgment
Controls > very preterm group
Left peristriate cortex	6	−14	−53	4	0.3
	5	−26	−86	−2	0.3
Left precuneus	9	−20	−61	42	0.3
