The deep opening that separates the two hemispheres is known as the longitudinal fissure. One of these, the falx cerebri, is a sickle-shaped partition lying between the two hemispheres of the brain. Also to Evolution plays a significant part, as The falx cerebri, so named from its sickle-like form, is a strong, arched process which descends vertically in the longitudinal fissure between the cerebral hemispheres.
The falx cerebri (aka falx, cerebral falx) is a an arched down fold of duramater that is found between the cerebral hemispheres in the interhemispheric fissure.
The thin nature of the tentorium cerebelli causes its contrast imaging to be low compared to surrounding tissues. With gadolinium-enhanced T1-weighted magnetic resonance imaging (MRI), the visibility of the tentorium is improved, however, a limiting factor is accessibility to the contrast .
