Table 1.

Location and MNI coordinates were given for the clusters with significant correlation between fractional anisotropy and WISC-RC math scores.

Statistical values		MNI coordinates anatomical location
Cluster size	t-value	x	y	z	Region
2808	4.13	−27	−66	44	L inferior longitudinal fasciculus
2071	4.6	−11	−77	32	L inferior longitudinal fasciculus
749	2.98	−33	−83	24	L inferior fronto-occipital fasciculus
673	4.03	−29	−7	−8	L inferior fronto-occipital fasciculus
578	3.88	27	−39	17	R inferior fronto-occipital fasciculus
482	4.68	−33	−47	47	L superior longitudinal fasciculus
476	3.75	−44	−62	35	L superior longitudinal fasciculus

The MNI coordinates and t-values for the local maxima of the centers of the clusters; R, right hemisphere; L, left hemisphere. The statistical threshold of all reported clusters were set at p < 0.05 using AlphaSim correction (with combination of threshold of p < 0.01 and a minimum cluster size of 473 voxels). The correlation analyses were adjusted for full-scale IQ, age and gender.
