| brain wave complex | A specific combination of fast and slow electroencephalographic activity that recurs frequently enough to be identified as a discrete phenomenon. (05 Mar 2000) |
|---|---|
| brain wave cycle | The complete upward and downward excursion of a single wave, complex, or impulse as seen on an electroencephalogram. (05 Mar 2000) |
| brain wave test | <investigation> A diagnostic test which measures the electrical activity of the brain (brain waves) using high sensitive recording equipment attached to the scalp by fine electrodes. Commonly employed in the evaluation of neurological disease (for example seizures, epilepsy, etc.). Acronym: EEG (13 Nov 1997) |
| Brain's reflex | Extension of the arm of a hemiplegic patient when turned prone as if on all fours. Synonym: Brain's reflex. (05 Mar 2000) |
| Brain, W Russell Lord | <person> English physician, 1895-1966. See: Brain's reflex. (05 Mar 2000) |
| brain-assocated tyrosine kinase | <enzyme> 86% identical to matk protein. Registry number: EC 2.7.1.- Synonym: batk protein (26 Jun 1999) |
| 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-heart infusion agar | A medium used for the isolation of fastidious microorganisms, especially fungi. (05 Mar 2000) |
| brain-specific kinase | <enzyme> Expressed specifically in brain; member of the eph/elk receptor-like kinase family; mw 105 kD; may represent murine homolog of chicken cek7 receptor-like kinase; amino acid sequence given in first source Registry number: EC 2.7.1.- Synonym: bsk tyrosine kinase (26 Jun 1999) |
| braincase | Those bones of the skull enclosing the brain, as distinguished from the bones of the face. Synonym: braincase, cranial vault, cranium cerebrale, cerebral cranium. Origin: neuro-+ G. Kranion, skull (05 Mar 2000) |
| brainstem | <anatomy> The lowest part of the brain, which merges with the spinal cord. It consists of the medulla oblongata, midbrain and pons. Originally, the entire unpaired subdivision of the brain, composed of (in anterior sequence) the rhombencephalon, mesencephalon, and diecephalon as distinguished from the brain's only paired subdivision, the telencephalon. More recently, the term's connotation has undergone several arbitrary modifications: some use it to denote no more than rhombencephalon plus mesencephalon, distinguishing that complex from the prosencephalon (diencephalon plus telencephalon); others restrict it even further to refer exclusively to the rhombencephalon. From both developmental and architectural viewpoints, the original interpretation seems preferable. (05 Mar 2000) |
| brainstem auditory evoked potentials | <investigation, physiology> A special neurologic test which measures the brainstem and brains nervous response to auditory stimulation. It is used to evaluate neurologic integrity and hearing in newborns. Can be used in the evaluation of stroke, acoustic neuroma, Meniere's disease and multiple sclerosis Acronym: BAEP (15 Nov 1997) |
| brainstem evoked response audiometry | An electrophysiologic measure of auditory function utilizing responses produced by the auditory nerve and the brainstem to repetitive acoustic stimuli. (05 Mar 2000) |
| brainstem glioma | <oncology, tumour> This primary brain tumour occurs in the pons or the medulla. They account for approximately 15% of brain tumours in children. Symptoms include double vision, facial weakness, vomiting and difficulty walking. Surgery is difficult due to location so radiation therapy and chemotherapy are used. Overall survival is 20 to 30%. (27 Sep 1997) |
