CG fiber pathways. A, 3D rendering of CG fiber pathways. To better visualize the fiber bundles, the 3D rendering is presented with the contralateral cortex and ipsilateral striatum after removal of the ipsilateral cortex from back coronal (top), lateral sagittal (middle), and dorsal horizontal (bottom) views. Note that axons traveling through the striatum to the thalamus and brainstem are intermixed and that two segregated thalamic fiber bundles could be identified. B, Schematic illustration of CG bundle subdivisions. C, Photomicrograph showing CG fibers traveling posteriorly toward the thalamus and brainstem as a large bundle in the center of the internal capsule. Top right, Coronal section for orientation. D, Photomicrograph of the CG–thalamic labeled fibers and thalamic terminals. CG axons leave the internal capsule and travel to the thalamus in a large, sparse bundle. Top right, Coronal section for orientation. AP, Anterior–posterior distance from bregma; BS, brainstem; Cn, contralateral fibers; Inj, injection site; Str/Th/BS, striatum/thalamus/brainstem; Th, thalamus; Th/BS, thalamus/brainstem.
