| cerebellothalamic tract | That component of the superior cerebellar peduncle (brachium conjunctivum) which originates in the cerebellar nuclei, crosses completely in the decussation of the brachia conjunctiva, bypasses the red nucleus, and terminates in parts of the ventral anterior, ventral intermediate, ventral posterolateral, and central lateral nuclei of the thalamus. Synonym: tractus cerebellothalamicus, dentatothalamic tract. (05 Mar 2000) |
| cerebellum | <anatomy> Part of the vertebrate hindbrain, concerned primarily with somatic motor function, the control of muscle tone and the maintenance of balance. Important model for cell migration in developing mammalian brain owing to well studied migratory pathway of the granule neuron and to the existence of the neurological mutant mouse weaver in which granule cell migration fails. (18 Nov 1997) |
| cerebr- | See: cerebro-. (05 Mar 2000) |
| cerebra | Plural of cerebrum. (05 Mar 2000) |
| cerebral | <anatomy> Of or pertaining of the cerebrum or the brain. (18 Nov 1997) |
| cerebral agraphia | The inability to express ideas in writing. Synonym: mental agraphia. (05 Mar 2000) |
| cerebral amyloid angiopathy | <pathology> A condition where there is a deposition of amyloid (insoluble protein) in the walls of the arteries which supply the brain. This results in an increased risk of dementia and-or intracerebral haemorrhage. Cerebral amyloidosis or cerebral amyloid angiopathy, is a complication of primary amyloidosis. Origin: Gr. Pathos = disease (27 Sep 1997) |

| cerebral aneurysm | A dilated and weakened portion of a cerebral blood vessel that is prone to rupture. A cerebral aneurysm may occur as a birth defect or develop as the result of long-standing poorly controlled hypertension. Symptoms of a ruptured cerebral aneurysm include a sudden, severe thunderclap headache that may be associated with nausea, vomiting and a decreased level of consciousness. (27 Sep 1997) |
| cerebral angiography | Radiography of the vascular system of the brain after injection of a contrast medium. (12 Dec 1998) |
| cerebral anoxia | A reduced supply of oxygen to the brain. (12 Dec 1998) |
| cerebral anthrax | A form of anthrax, associated with pulmonary or intestinal anthrax, in which the specific bacilli invade the capillaries of the brain causing violent delirium; frequently associated with haemorrhagic meningitis. (05 Mar 2000) |
| cerebral aqueduct | An ependymal-lined canal in the mesencephalon about 20 mm long, connecting the third to the fourth ventricle. Synonym: aqueductus cerebri, aqueduct of cerebrum, aqueductus sylvii, iter a tertio ad quartum ventriculum, sylvian aqueduct. (05 Mar 2000) |
| cerebral arterial circle | The roughly pentagonally shaped circle of vessels on the ventral aspect of the brain in the area of the optic chiasm, hypothalamus, and interpeduncular fossa. See: circle of Willis. (05 Mar 2000) |
