This page is a dumping ground for anatomical terms that come up in conversation with neuroscientists, phrased (hopefully!) in a way that CS people can understand them. Click a tract name for specific information, including instructions for segmenting the tract out of a tractogram in Brainapp.
- Corpus Callosum (CC)
- The large tract connecting the hemispheres. In a mid-sagittal cutting plane, it looks like a letter C turned on its side, with the tips pointing inferior.
- Genu
- The anterior part of the CC, where it bends back on itself. "Genu" means "knee".
- Splenium
- The posterior part of the CC.
- Rostrum
- The part of the CC inferior and posterior to the genu.
- Forceps major / forceps posterior
- The posterior projection of the CC (from the splenium) into the occipital lobe. In a transverse cutting plane, it looks like a letter C at the posterior portion of the brain with the tips pointing posterior.
- Forceps minor / forceps anterior
- The anterior projection of the CC (from the genu) into the cerebrum. In a transverse cutting plane, it looks like a letter C at the anterior portion of the brain with the tips pointing anterior. In other words, it looks sort of like a pair of mandibles over the eyes.
- Corona radiata
- A fan-shaped sheet of WM that radiates from the brain stem superior to the cortex.
- Superior longitudinal fasciculus (SLF)
- ???
- Cingulum
- ???
- Corticospinal tract (CST)
- ???
