The superior cistern (located dorsal to the midbrain) together with the subarachnoid space at the sides of the midbrain are referred to clinically as the cisterna ambiens. The superior cistern is important because it contains internal cerebral veins, which join caudally to form the great cerebral vein (of Galen).

The Sylvian cistern , which is known as the insular cistern, is located between the temporal (lower lobe of the cortex) and frontal lobes (control essential human cognitive functions)(12). This cistern contains some arteries, including the middle cerebral artery (terminal branch of the internal carotid artery)(13).
