| primary brain tumour | <neurology, oncology> May be subdivided into primary brain tumours and the more common, secondary brain tumours. Primary brain tumours (for example astrocytoma, craniopharyngioma, glioma, ependymoma, neuroglioma, oligodendroglioma, glioblastoma multiforme, meningioma, medulloblastoma) arise from the uncontrolled proliferation of cells within the brain. Secondary brain tumours occur from the spread of cancer into the brain from a distant cancerous organ (metastasis). Common symptoms of a brain tumour include headache, nausea, vomiting, seizures, change in mentation, neurologic symptoms and loss of memory. (06 Mar 1998) |
| 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) |
