| primary brain vesicle | Each of the three divisions of the early embryonic brain (prosencephalon, mesencephalon, and rhombencephalon). Synonym: encephalic vesicle, primary brain vesicle. (05 Mar 2000) |

| smell-brain | Origin: NL, fr. Gr, the nose + the brain. <anatomy> The division of the brain in front of the prosencephalon, consisting of the two olfactory lobes from which the olfactory nerves arise. The term is sometimes used for one of the olfactory lobes, the plural being used for the two taken together. Source: Websters Dictionary (01 Mar 1998) |
| split brain | A brain in which the corpus callosum and usually the anterior and posterior commissures have been sectioned; usually to treat certain refractory epilepsies. (05 Mar 2000) |
| developmental brain tumours | <radiology> 1% of all brain tumours, germ-cell tumours, epidermoid more than dermoid more than > Teratoma, usually midline, craniopharyngioma, colloid cyst, lipoma, hamartoma (12 Dec 1998) |
| diffuse brain atrophy | A form of dementia caused by destruction (atrophy) of the frontal lobes of the brain. This condition leads to the progressive deterioration of mental functioning. Incidence: 9 in 10,000 people in the general population. (27 Sep 1997) |
| dura mater of brain | The intracranial dura mater, consisting of two layers: the outer periosteal layer which normally always adheres to the periosteum of the bones of the cranial vault; and the inner meningeal layer which in most places is fused with the outer. The two layers separate to accommodate meningeal vessels and large venous (dural) sinuses. The meningeal layer is also involved in the formation of the various dural folds, such as the falx cerebri and tentorium cerebelli and is comparable to and continuous with the dural mater of the spinal cord. The cranial epidural space is then a potential space between the bone and the combined periosteum/periosteal layer of the dura mater realised only pathologically and is neither continuous with or comparable to the vertebral epidural space. Synonym: dura mater cranialis, dura mater encephali, cerebral part of dura mater, cranial epidural space. (05 Mar 2000) |
| infantile brain tumours | <radiology> Can be present at birth: choroid plexus papilloma, medulloblastoma, craniopharyngioma, ependymoma, astrocytoma, teratoma (12 Dec 1998) |
| organic brain syndrome | <syndrome> A constellation of behavioural or psychological signs and symptoms including problems with attention, concentration, memory, confusion, anxiety, and depression caused by transient or permanent dysfunction of the brain. Synonym: acute organic brain syndrome, OBS, organic mental syndrome. (05 Mar 2000) |
| enhancing brain nodule | <radiology> Metastases, infection, cysticercosis, histoplasmosis, tuberculosis, non-infectious inflammatory processes, sarcoidosis, multiple sclerosis, primary CNS lymphoma, subacute multiple infarcts see: ring lesions in brain (12 Dec 1998) |
| twixt-brain | <anatomy> The thalamencephalon. Source: Websters Dictionary (01 Mar 1998) |
| lateral fossa of brain | The deep depression of the basal surface of the forebrain that corresponds in position to the anterior perforated substance. Bounded medially by the optic tract and rostrally by the orbital surface of the frontal lobe, it extends laterally around the overhanging pole of the temporal lobe into the Sylvian fissure (sulcus lateralis). Synonym: fossa lateralis cerebri, fossa of Sylvius, lateral fossa of brain, vallecula sylvii. (05 Mar 2000) |
| breast cancer susceptibility genes | Inherited factors that predispose to breast cancer. Put otherwise, these genes make one more susceptible to the disease and so increase the risk of developing breast cancer. Two of these genes, BRCA1 and BRCA2, have been identified (and prominently publicised). Several other genes (those for the Li-Fraumeni syndrome, Cowden disease, Muir-Torre syndrome, and ataxia-telangiectasia) are also known to predispose to breast cancer. However, since all of these known breast cancer susceptibility genes together do not account for more than a minor fraction (1/5th at most) of breast cancer that clusters in families, it is clear that more breast cancer genes remain to be discovered.

| genes | Located in the nucleus of the cell, genes contain hereditary information that is transferred from cell to cell. (09 Oct 1997) |
| genes, abl | Retrovirus-associated DNA sequences (abl) originally isolated from the abelson murine leukaemia virus (ab-mulv). The proto-oncogene abl (c-abl) codes for a protein that is a member of the tyrosine kinase family. The human c-abl gene is located at 9q34.1 on the long arm of chromosome 9. It is activated by translocation to bcr on chromosome 22 in chronic myelogenous leukaemia. (12 Dec 1998) |
