| brain cicatrix | A scarring of the brain resulting from injury (reactive gliosis), characterised by proliferation of mesodermal (vascular) and ectodermal (glial) elements. See: isomorphous gliosis. (05 Mar 2000) |

| brain concussion | Transient or prolonged unconsciousness with or without impairment of higher mental functions and/or brainstem functions, due to a violent blow to the head. (12 Dec 1998) |
| brain congestion | Increased volume of the intravascular compartment of the brain; often associated with brain swelling. Synonym: encephalaemia. (05 Mar 2000) |
| brain contusion | A head injury of sufficient force to bruise the brain. The bruising of the brain will often involve the surface of the brain and cause an extravasation of blood without rupture of the pia-arachnoid. Often associated with a concussion. (27 Sep 1997) |
| brain death | Total cessation of brain function for 24 hours as manifested by absence of spontaneous movement, absence of spontaneous respiration, and absence of all brainstem reflexes. (12 Dec 1998) |
| brain-derived growth factor | <growth factor> Small basic protein purified from pig brain, a member of the family of neurotrophic factors that also includes Nerve Growth Factor and neurotrophin 3. In contrast to nerve growth factor, brain-derived neurotrophic factor is predominanantly (though not exclusively) localised in the CNS. It supports the survival of primary sensory neurons originating from the neural crest and ectodermal placodes that are not responsive to NGF. In the brain brain-derived neurotrophic factor has a trophic action on retinal, cholinergic, and dopaminergic neurons, and in the peripheral nervous system it acts on both motor and sensory neurons. Acronym: BDGF (12 Dec 1998) |

| brain diseases, metabolic | Metabolic disorders which lead to pathological changes and/or functional deviations of the brain. (12 Dec 1998) |
| brain-heart infusion agar | A medium used for the isolation of fastidious microorganisms, especially fungi. (05 Mar 2000) |
| brain herniation | A condition that occurs when the brain is under abnormally increased pressure. The increased intracranial pressure forces the brain downward inside the skull. This results in typical neurologic manifestations (coma, paralysis and a unilateral dilated pupil). May occur secondary to head injury, primary or metastatic brain tumour, bacterial meningitis and brain abscess. Brain herniations may involve different portions of the brain such as the cerebellum (cerebellar herniation), uncus (uncal herniation) and transtentorial herniation of the cerebrum. (27 Sep 1997) |
| brain injury | Acute injuries to the brain, general or unspecified. (12 Dec 1998) |

| brain laceration | Gross tearing of neural tissue. (05 Mar 2000) |
| brain lipid | Impure cephalin possessing marked haemostatic action when locally applied. (05 Mar 2000) |
| brain mantle | Origin: L. See Pall the garment. 1. A large, square, woolen cloak which enveloped the whole person, worn by the Greeks and by certain Romans. It is the Roman name of a Greek garment. 2. A band of white wool, worn on the shoulders, with four purple crosses worked on it; a pall. The wool is obtained from two lambs brought to the basilica of St. Agnes, Rome, and blessed. It is worn by the pope, and sent to patriarchs, primates, and archbishops, as a sign that they share in the plenitude of the episcopal office. Befoer it is sent, the pallium is laid on the tomb of St. Peter, where it remains all night. 3. <zoology> The mantle of a bivalve. See Mantle. The mantle of a bird.
