- Great longitudinal fissure
- Medial longitudinal fissure
The interhemispheric fissure, also known as the medial longitudinal fissure, is the deep groove within the midline separating both cerebral hemispheres and containing the falx cerebri. Being a fissure, it also contains CSF as well as some midline branches of the ACA and PCA.
