Brain's Reflex
Brain's reflex is the extension of a hemiplegic flexed arm when a quadrupedal posture is assumed by a human subject. It was first described by Russell Brain, a British neurologist Neurology (from el, νεῦρον (neûron), "string, nerve" and the suffix -logia, "study of") is the branch of medicine dealing with the diagnosis and treatment of all categories of conditions and disease involving the brain, the spinal c ....''Encyclopædia Britannica'' References Reflexes {{med-sign-stub ...

Hemiplegia
Hemiparesis, or unilateral paresis, is weakness of one entire side of the body ('' hemi-'' means "half"). Hemiplegia is, in its most severe form, complete paralysis of half of the body. Hemiparesis and hemiplegia can be caused by different medical conditions, including congenital causes, trauma, tumors, or stroke.Detailed article about hemiparesis at Disabled-World.com Signs and symptoms Depending on the type of hemiparesis diagnosed, different bodily functions can be affected. Some effects are expected (e.g., partial paralysis of a limb on the affected side). Other impairments, though, can at first seem completely non-related to the limb weakness but are, in fact, a direct result of the damage to the affected side of the brain. Loss of m ...

Quadrupedalism
Quadrupedalism is a form of locomotion where four limbs are used to bear weight and move around. An animal or machine that usually maintains a four-legged posture and moves using all four limbs is said to be a quadruped (from Latin ''quattuor'' for "four", and ''pes'', ''pedis'' for "foot"). Quadruped animals are found among both vertebrates and invertebrates. Quadrupeds vs. tetrapods Although the words ‘quadruped’ and ‘tetrapod’ are both derived from terms meaning ‘four-footed’, they have distinct meanings. A tetrapod is any member of the taxonomic unit Tetrapoda (which is defined by descent from a specific four-limbed ancestor), whereas a quadruped actually uses four limbs for locomotion. Not all tetrapods are quadrupeds and not all entities that could be described as ‘quadrupedal’ are tetrapods. This last meaning includes certain artificial objects; almost all quadruped ''organisms'' are tetrapods (with the exception of some raptorial arthropods adapted fo ...

Russell Brain, 1st Baron Brain
Walter Russell Brain, 1st Baron Brain (23 October 1895 – 29 December 1966) was a British neurologist. He was principal author of the standard work of neurology, ''Brain's Diseases of the Nervous System'', and longtime editor of the homonymous neurological medical journal titled ''Brain''. He is also eponymised with "Brain's reflex", a reflex exhibited by humans when assuming the quadrupedal position. Career Brain was educated at Mill Hill School and New College, Oxford, where he began to read history, but disliked it. The First World War having begun in 1914, the following year he joined the Friends' Ambulance Unit as an alternative to volunteering for combat, and was sent to York, moving later to the King George Hospital in London, attached to the X-ray department. On the introduction of conscription in 1916 his work enabled him to be exempted as a conscientious objector. After the war he returned to New College, and studied medicine, obtaining his BM BCh in 1922 and a D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neurologist
Neurology (from el, νεῦρον (neûron), "string, nerve" and the suffix -logia, "study of") is the branch of medicine dealing with the diagnosis and treatment of all categories of conditions and disease involving the brain, the spinal cord and the peripheral nerves. Neurological practice relies heavily on the field of neuroscience, the scientific study of the nervous system. A neurologist is a physician specializing in neurology and trained to investigate, diagnose and treat neurological disorders. Neurologists treat a myriad of neurologic conditions, including stroke, seizures, movement disorders such as Parkinson's disease, autoimmune neurologic disorders such as multiple sclerosis, headache disorders like migraine and dementias such as Alzheimer's disease. Neurologists may also be involved in clinical research, clinical trials, and basic or translational research. While neurology is a nonsurgical specialty, its corresponding surgical specialty is neurosurgery. Histor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
