What is the term for the groove that separates the two cerebral hemispheres?

Explanation:
The longitudinal fissure is the midline groove that runs from front to back, splitting the brain into left and right cerebral hemispheres. It’s also called the interhemispheric fissure, and the falx cerebri sits within it. By contrast, the central sulcus lies within a single hemisphere and separates the frontal and parietal lobes, the Sylvian (lateral) fissure separates temporal from frontal/parietal regions on the lateral surface, and the transverse fissure separates the cerebrum from the cerebellum. So the groove that truly separates the two hemispheres is the longitudinal fissure.
