| superficial middle cerebral vein | <anatomy, vein> A large vein passing along the line of the sylvian fissure to join the cavernous sinus; it communicates with the superior sagittal sinus and transverse sinus via the superior and inferior anastomotic veins, respectively. Synonym: vena cerebri media superficialis. (05 Mar 2000) |

| superior cerebral veins | Numerous (8 to 10) veins that drain the dorsal convexity of the cortical hemisphere and empty into the superior sagittal sinus, curving rostrally in passing through the subdural space so as to enter the sinus at an acute forward angle. Synonym: venae cerebri superiores. (05 Mar 2000) |
| superolateral cerebral surface | The aspect of the cerebral hemisphere that lies in contact with the flat bones of the skull; it includes parts of the frontal, parietal, temporal, and occipital lobes. Synonym: facies superolateralis cerebri, cortical convexity, superolateral cerebral surface. (05 Mar 2000) |
| deep cerebral veins | The numerous veins draining the deep structures of the cerebral hemispheres; they empty into the tributaries of the great cerebral vein. Synonym: venae cerebri profundae. (05 Mar 2000) |
| deep middle cerebral vein | <anatomy, vein> The vein that accompanies the middle cerebral artery in the depths of the lateral sulcus and empties into the basal vein of Rosenthal. Synonym: vena cerebri media profunda. (05 Mar 2000) |

| internal cerebral veins | Paired veins passing caudally near the midline in the tela choroidea of the third ventricle, formed by the union of the choroid vein, thalamostriate (terminal) vein, and vein of septum pellucidum, and uniting caudally so as to form the great cerebral vein. Synonym: venae cerebri internae, veins of Galen. (05 Mar 2000) |
| occipital cerebral veins | The superior cerebral veins draining the occipital cortex and emptying into the superior sagittal sinus and the transverse sinus. Synonym: venae occipitales. (05 Mar 2000) |
| opening to cerebral aqueduct | Entrance to the cerebral aqueduct (of Sylvius) from the caudal part of the third ventricle. Synonym: aditus ad aqueductum cerebri, Bartholin's anus, opening to cerebral aqueduct. (05 Mar 2000) |
| toxoplasmosis, cerebral | Infection caused by the protozoan toxoplasma that presents itself in a subacute fashion with headache, focal neurologic signs, seizures, or altered mental status which can progress to coma. This condition is a commonly encountered opportunistic infection in aids patients. (12 Dec 1998) |
