Henri Meige
Henri Meige (11 February 1866 – 29 September 1940) was a French neurologist born in Moulins-sur-Allier. He characterized Meige's syndrome in 1910. He studied medicine in Paris under Jean Charcot (1825–1893), earning his doctorate in 1893. Afterwards he worked at the Salpêtrière and the École nationale supérieure des Beaux-Arts, École des Beaux-Arts, where in the 1920s he was appointed professor. With Édouard Brissaud (1852–1909) he researched skeletal changes in acromegaly, concluding that gigantism in adolescents is fundamentally the same disease as acromegaly in adults. During World War I he conducted studies of neuropathy with Pierre Marie (1853–1940). Meige is best known for his work with extrapyramidal system, extrapyramidal lesions. In 1902, with Eugene Feindel, he published an important work on motor system, motor disturbances, blepharospasms and tics. In contrast to Charcot, Meige asserted that disturbances of the extrapyramidal system were manifestations ... [...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] |
Extrapyramidal System
In anatomy, the extrapyramidal system is a part of the motor system network causing involuntary actions. The system is called ''extrapyramidal'' to distinguish it from the tracts of the motor cortex that reach their targets by traveling through the pyramids of the medulla. The pyramidal tracts (corticospinal tract and corticobulbar tracts) may directly innervate motor neurons of the spinal cord or brainstem ( anterior (ventral) horn cells or certain cranial nerve nuclei), whereas the extrapyramidal system centers on the modulation and regulation (indirect control) of anterior (ventral) horn cells. Extrapyramidal tracts are chiefly found in the reticular formation of the pons and medulla, and target lower motor neurons in the spinal cord that are involved in reflexes, locomotion, complex movements, and postural control. These tracts are in turn modulated by various parts of the central nervous system, including the nigrostriatal pathway, the basal ganglia, the cerebellum, the vesti ...

1940 Deaths
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Jules Séglas
Jules Séglas (May 31, 1856 – 1939) was a French psychiatrist who practiced medicine at the Bicêtre and Salpêtrière Hospitals in Paris. Early in his career, he was an assistant to famed neurologist Jean-Martin Charcot (1825–1893). Séglas' ideas and theories influenced a number of psychiatrists, including Henri Ey (1900–1977) and Jacques Lacan (1901–1981). In 1908 he became president of the ''Societé Medico-Psychologique''. In the field of psychopathology he conducted studies of delusions, hallucinations and pseudohallucinations, providing a detailed nosology of these phenomena. He did extensive research of language and its relationship to mental illness. Here, he described linguistic traits such as logorrhea, embolalia, near-mutism, automatic speech, alexia, agraphia, et al.; and how these behaviors take shape and interact in various psychiatric disorders.

Pyramidal Tract
The pyramidal tracts include both the corticobulbar tract and the corticospinal tract. These are aggregations of efferent nerve fibers from the upper motor neurons that travel from the cerebral cortex and terminate either in the brainstem (''corticobulbar'') or spinal cord (''corticospinal'') and are involved in the control of motor functions of the body. The corticobulbar tract conducts impulses from the brain to the cranial nerves. These nerves control the muscles of the face and neck and are involved in facial expression, mastication, swallowing, and other motor functions. The corticospinal tract conducts impulses from the brain to the spinal cord. It is made up of a lateral and anterior tract. The corticospinal tract is involved in voluntary movement. The majority of fibres of the corticospinal tract cross over in the medulla oblongata, resulting in muscles being controlled by the opposite side of the brain. The corticospinal tract contains the axons of the pyramidal cell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tics
A tic is a sudden, repetitive, nonrhythmic motor movement or vocalization involving discrete muscle groups.American Psychiatric Association (2000)DSM-IV-TR: Tourette's Disorder.''Diagnostic and Statistical Manual of Mental Disorders'', 4th ed., text revision (DSM-IV-TR), . Available at BehaveNet.com Retrieved on August 10, 2009. Tics can be invisible to the observer, such as abdominal tensing or toe crunching. Common motor and phonic tics are, respectively, eye blinking and throat clearing. Tics must be distinguished from movements of disorders such as chorea, dystonia and myoclonus; the compulsions of obsessive–compulsive disorder (OCD) and seizure activity; and movements exhibited in stereotypic movement disorder or among autistic people (also known as stimming). Classification Tics are classified as either motor or phonic, and simple or complex. Motor or phonic Motor tics are movement-based tics affecting discrete muscle groups. Phonic tics are involuntary sounds prod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blepharospasm
Blepharospasm is any abnormal contraction of the orbicularis oculi muscle. The condition should be distinguished from the more common, and milder, involuntary quivering of an eyelid, known as myokymia, or fasciculation. In most cases, blepharospasm symptoms last for a few days and then disappear without treatment, but in some cases the twitching is chronic and persistent, causing life-long challenges. In these cases, the symptoms are often severe enough to result in functional blindness. The person's eyelids feel like they are clamping shut and will not open without great effort. People have normal eyes, but for periods of time are effectively blind due to their inability to open their eyelids. In contrast, the reflex blepharospasm is due to any pain in and around the eye. It is of two types: essential and reflex blepharospasm. The benign essential blepharospasm (BEB) is a focal dystonia—a neurological movement disorder involving involuntary and sustained contractions of the m ...

Motor System
The motor system is the set of central and peripheral structures in the nervous system that support motor functions, i.e. movement. Peripheral structures may include skeletal muscles and neural connections with muscle tissues. Central structures include cerebral cortex, brainstem, spinal cord, pyramidal system including the upper motor neurons, extrapyramidal system, cerebellum, and the lower motor neurons in the brainstem and the spinal cord. Pyramidal motor system The pyramidal motor system, also called the pyramidal tract or the corticospinal tract, start in the motor center of the cerebral cortex.Rizzolatti G, Luppino G (2001) The Cortical Motor System. ''Neuron'' 31: 889-90SD/ref> There are upper and lower motor neurons in the corticospinal tract. The motor impulses originate in the giant pyramidal cells or Betz cells of the motor area; i.e., precentral gyrus of cerebral cortex. These are the upper motor neurons (UMN) of the corticospinal tract. The axons of these cel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pierre Marie
Pierre Marie (9 September 1853 – 13 April 1940) was a French neurologist and political journalist close to the SFIO. Medical Career After finishing medical school, he served as an interne (1878), working as an assistant to neurologist Jean-Martin Charcot (1825–1893) at the Salpêtrière and Bicêtre Hospitals in Paris. In 1883 he received his medical doctorate with a graduate thesis on Basedow’s disease, being promoted to ''médecin des hôpitaux'' several years later (1888). In 1907 he attained the chair of pathological anatomy at the Faculty of Medicine, and in 1917 was appointed to the chair of neurology, a position he held until 1925. In 1911 Marie became a member of the ''Académie de Médecine''. One of Marie's earlier contributions was a description of a disorder of the pituitary gland known as acromegaly. His analysis of the disease was an important contribution in the emerging field of endocrinology. Marie is also credited as the first to describe pulmonary hy ...

Moulins-sur-Allier
Moulins (; oc, Molins) is a commune in central France, capital of the Allier department. It is located on the river Allier. Among its many tourist attractions are the Maison Mantin, the Anne de Beaujeu Museum and The National Center of Costume and Scenography. Geography Moulins is located on the banks of the river Allier. History Before the French Revolution, Moulins was the capital of the province of Bourbonnais and the seat of the Dukes of Bourbon. It appears in documented records at least as far back as the year 990. In 1232, Archambaud VIII, Sire de Bourbon granted a franchise to the village's inhabitants. The town achieved greater prominence in 1327, when Charles IV elevated Louis I de Clermont to Duke of Bourbon. Either Louis or the later Peter II, Duke of Bourbon and of Auvergne moved the capital of the province from Bourbon-l'Archambault to Moulins. :''Note: This article in French suggests Pierre II moved the capital, while thlocal tourism website(also in Fren ...
