Anatomy and function
The corpus callosum is a major commissural fibre structure connecting the two cerebral hemispheres. It forms an upward-curving arch at the base of the longitudinal fissure.
Where to look in the model
The fsaverage aseg corpus callosum segmentation, labels 251–255, lies in the midline above the thalami.
What this view does not establish
Individual axons, tractography results and precise fibre-bundle distributions are not drawn.
Open in 3DSources and precision
Cortex uses the FreeSurfer fsaverage5 template surface, with 10,242 vertices per hemisphere. Functional references use selected Destrieux sulcal and gyral parcels. Deep structures use fsaverage aseg segmentations. The Sereno2020 cerebellar research surface preserves folial geometry, but comes from another specimen; its assembled placement is schematic, without medical registration across templates. Arterial paths are manually drawn teaching schematics, not CTA/MRA reconstructions.
An educational schematic prototype for understanding spatial relationships. Item-by-item independent neuroanatomical review is pending. Functional highlights are not results of an individual examination and do not support individual diagnosis or treatment decisions.
