Fig 3. Cerebrocerebellar connections illustrating the relation between volumes in structures within the afferent pathway (cerebellothalamocortical structures connected by arrows with double lines) and the efferent pathway (corticopontocerebellar structures connected by arrows with solid lines). The relation between dorsolateral prefrontal cortex and the cerebellum is indicated by arrows with dotted lines. ns indicates statistically not significant (P > 0.05).

Fig 4. T1WI sagittal (A), T2WI axial (B), and T1WI coronal (C) images of the cerebellum from a 16-year-old boy with TBI (initial GCS = 3) and a TD child of comparable age and sex (DF). The child with TBI has diffuse cerebellar atrophy and increased CSF within the cerebellar folia that can be noted in all planes.
