Schematic representation of decussating lobewise cerebrocerebellar tracts. Lobewise afferent cerebro-pontine-cerebellar fibres and efferent cerebello-rubro-thalamic fibres, as connected to their cerebellar representation on the combined probability map. Frontal (orange); Occipital (magenta); Parietal (blue); Temporal (green). From the cerebral cortex, the cerebro-pontine-cerebellar fibres descend thought the ipsilateral crus cerebri to reach the basal pontine nuclei, after which they cross to the contralateral side and enter the cerebellum. The cerebello-rubro-thalamic-cerebral fibres leave the cerebellum, decussate in the caudoventral mesencephalon and are relayed to the cerebral lobes by the nucleus ruber and thalamus.⁴⁷^,⁴⁸
