Tractography of crossed reciprocal tracts between the CB-BG and cortical targets in a representative subject. Tracts are superimposed on the study template (3D view, and axial views for a display of the tract trajectory). (A) Ascending cerebellum basal ganglia tracts; From left to right, Tracts between Right DN and Left Putamen, traversing Left Thalamus; Tracts between Left DN and Right Putamen, traversing Right Thalamus. (B) Descending cerebellum basal ganglia tracts; In the clockwise direction, Tracts between Right STN and contralateral Cerebellar cortex, C7b Left; Tracts between Left STN and contralateral Cerebellar cortex, C7b Right; Tracts between Right STN and contralateral Cerebellar cortex, C7b Left; Tracts between Left STN and contralateral CB cortex, Crus II Right; Tracts between Right STN and contralateral Cerebellar cortex, Crus II Left; (C) Cerebellar cortical tracts; From top to bottom, the first row shows the tracts between the DN and the sensorimotor cortex traversing the ventral intermediary nucleus of the thalamus. The top and bottom rows display axial views of the right CB-left thalamus/Cortex and left CB-right Thalamus/Cortex respectively; The second row shows the tracts between the DN to the contralateral mPFC/ACC via the medial dorsal nuclei of the thalamus. The top and bottom rows display axial views of the left CB-right Thalamus/Cortex and right CB-left thalamus/Cortex, respectively. The third row shows the tracts from the dentate to the contralateral mPFC/ACC via the ventral tegmental area.
