Regions of significantly increased fractional anisotropy in conduct disordered adolescents compared to healthy controls.
Key: R-right; L- left; A-anterior; P-posterior; green indicates mean FA (fractional anisotropy) skeleton; red denotes areas of significantly greater (p < .05) FA in CD in: (i) bilateral superior cerebellar peduncle; (ii) left cerebellar white matter; (iii) right superior longitudinal fasciculus; (iv) bilateral corticopontocerebellar tract; (v) bilateral posterior limb of internal capsule; (vi) bilateral inferior cerebellar peduncle; (vii) bilateral corticospinal tract; (viii) bilateral corticopontocerebellar tract

Correlations between FA and behavioural measures in whole sample (above) and by group (below). There were significant correlations between: 1) SDQ total problems and FA of the bilateral corticospinal tract, posterior limb of the internal capsule, superior cerebellar peduncle, and corticopontocerebellar tract; left cerebellar WM; and the right inferior cerebellar peduncle, and superior longitudinal fasciculus; 2) SDQ conduct problems and FA of the bilateral corticospinal tract, posterior limb of the internal capsule, superior cerebellar peduncle, inferior cerebellar peduncle, and corticopontocerebellar tract; and left cerebellar WM; 3) APSD total problems and FA of the bilateral inferior cerebellar peduncle; left cerebellar WM; and the right posterior limb of the internal capsule, superior longitudinal fasciculus, and corticopontocerebellar tract; 4) APSD callous-unemotional traits and FA of the right posterior limb of the internal capsule, superior longitudinal fasciculus, corticopontocerebellar tract; and left cerebellar WM; and 5) APSD impulsivity and the right inferior cerebellar peduncle.
