Abstract:
Post-mortem connectivity based methods demonstrate that the cerebellar dentate nuclei act as the main center of communication to the cerebral cortex. Dentate nuclei have a contralateral connection with the cerebral cortex. However, direct invivo diffusion imaging of this crossing and of the dentate projections to the cortex via crossing is lacking. diffusion-tractography with integration of resting-state-fMRI is used to investigate the dentate-thalamocortical circuit. The results inflect the dentate nuclei connectivity with the contralateral cortical regions via the thalamic nuclei i.e. motor, posterior-parietal, frontal, and temporal regions. In the study, connectivity based organization about the output-channels within the dentate is introduced. The study holds promise for clinical applications.
