Guillaume Benjamin Amand Duchenne
Guillaume-Benjamin-Amand Duchenne (de Boulogne) (September 17, 1806 in Boulogne-sur-Mer – September 15, 1875 in Paris) was a French neurologist who revived Galvani's research and greatly advanced the science of electrophysiology. The era of modern neurology developed from Duchenne's understanding of neural pathways and his diagnostic innovations including deep tissue biopsy, nerve conduction tests ( NCS), and clinical photography. This extraordinary range of activities (mostly in the Salpêtrière) was achieved against the background of a troubled personal life and a generally indifferent medical and scientific establishment. Neurology did not exist in France before Duchenne and although many medical historians regard Jean-Martin Charcot as the father of the discipline, Charcot owed much to Duchenne, often acknowledging him as "''mon maître en neurologie''" (my master in neurology). The American neurologist Dr. Joseph Collins (1866–1950) wrote that Duchenne found neurolo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mécanisme De La Physionomie Humaine
''Mécanisme de la physionomie humaine. ou, Analyse électro-physiologique de l'expression des passions des arts plastiques.'' is a monograph on the muscles of facial expression, researched and written by Guillaume-Benjamin-Amand Duchenne de Boulogne (1806–75). It first appeared as an abstract published in ''Archives générales de médecine'' in 1862 and was then published in three formats: two octavo editions and one quarto edition. The work was an important resource used by Charles Darwin (1809–82) for his own study on the genetics of behaviour, titled '' The Expression of Emotions in Man and Animals'', and in recent years it has been reclaimed as an important landmark in the history of the photographic arts. Overview Influenced by the fashionable beliefs of Physiognomy of the 19th century, Duchenne wanted to determine how the muscles in the human face produce facial expressions which he believed to be directly linked to the soul of man. He is known, in particular, for the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

French Academy Of Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV of France, Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French Scientific method, scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academy of Sciences, Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque nationale de France, Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Smile
A smile is a facial expression formed primarily by flexing the muscles at the sides of the mouth. Some smiles include a contraction of the muscles at the corner of the eyes, an action known as a Duchenne smile. Among humans, a smile expresses delight, sociability, happiness, joy, or amusement. It is distinct from a similar but usually involuntary expression of anxiety known as a grimace. Although cross-cultural studies have shown that smiling is a means of communication throughout the world, there are large differences among different cultures, religions, and societies, with some using smiles to convey confusion or embarrassment. Evolutionary background Primatologist Signe Preuschoft traces the smile back over 30 million years of evolution to a "fear grin" stemming from monkeys and apes, who often used barely clenched teeth to portray to predators that they were harmless or to signal submission to more dominant group members. The smile may have evolved differently among spe ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Electro-therapeutics
Electrotherapy is the use of electrical energy as a medical treatment. In medicine, the term ''electrotherapy'' can apply to a variety of treatments, including the use of electrical devices such as deep brain stimulation, deep brain stimulators for neurological disease. The term has also been applied specifically to the use of electric current to speed wound healing. Additionally, the term "electrotherapy" or "electromagnetic therapy" has also been applied to a range of alternative medicine, alternative medical devices and treatments. Medical uses Electrotherapy is primarily used in physical therapy for: * relaxation of muscle spasms * prevention and retardation of disuse atrophy * increase of local blood circulation * muscle rehabilitation and re-education * electrical muscle stimulation * maintaining and increasing range of motion * management of chronic and intractable pain including diabetic neuropathy * acute post-traumatic and post-surgical pain * post-surgical stimulati ...

Medical Science
Medicine is the science and practice of caring for a patient, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others. Medicine has been practiced since prehistoric times, and for most of this time it was an art (an area of skill and knowledge), frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healing, or an ancie ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Farad
The farad (symbol: F) is the unit of electrical capacitance, the ability of a body to store an electrical charge, in the International System of Units (SI). It is named after the English physicist Michael Faraday (1791–1867). In SI base units 1 F = 1 kg−1⋅ m−2⋅ s4⋅ A2. Definition The capacitance of a capacitor is one farad when one coulomb of charge changes the potential between the plates by one volt. Equally, one farad can be described as the capacitance which stores a one-coulomb charge across a potential difference of one volt. The relationship between capacitance, charge, and potential difference is linear. For example, if the potential difference across a capacitor is halved, the quantity of charge stored by that capacitor will also be halved. For most applications, the farad is an impractically large unit of capacitance. Most electrical and electronic applications are covered by the following SI prefixes: *1 mF (millifarad, one thousandth ...

Jean-Baptiste Sarlandière
Jean-Baptiste Sarlandière (9 May 1787 – 25 July 1838) was a French anatomist and physiologist born in Aix-la-Chapelle. At the age of 16 he began his medical studies at the local hospital in Noirmoutiers, but was soon called to military service, spending the next eleven years as part of the French Army (1803–1814). In 1814 he resumed his studies, and subsequently was appointed physician at the military hospital in Paris. He received his medical degree in 1815 with a thesis titled ''Effets des cosmétiques chez les dames''. In Paris, Sarlandière became a friend and assistant to François Magendie (1783–1855), with whom he collaborated on several physiological experiments. Sarlandière is remembered for introducing electroacupuncture to European medicine, a therapeutic technique that combined electricity with acupuncture. Unlike Oriental acupuncture, the needle was not the primary agent of treatment, but simply acted as a conductor to apply the electricity subcutaneously. ...

François Magendie
__NOTOC__ François Magendie (6 October 1783 – 7 October 1855) was a French physiologist, considered a pioneer of experimental physiology. He is known for describing the foramen of Magendie. There is also a ''Magendie sign'', a downward and inward rotation of the eye due to a lesion in the cerebellum. Magendie was a faculty at the College of France, holding the Chair of Medicine from 1830 to 1855 (he was succeeded by Claude Bernard, who worked previously as his assistant). In 1816 he published ''Précis élementaire de Physiologie'' which described an experiment first illustrating the concept of empty calories: :I took a dog of three years old, fat, and in good health, and put it to feed upon sugar alone...It expired the 32nd day of the experiment. His most important contribution to science was also his most disputed. Contemporaneous to Sir Charles Bell, Magendie conducted a number of experiments on the nervous system, in particular verifying the differentiation between ...

Guillaume Dupuytren
Baron Guillaume Dupuytren (; 5 October 1777 – 8 February 1835) was a French anatomist and military surgeon. Although he gained much esteem for treating Napoleon Bonaparte's hemorrhoids, he is best known today for his description of Dupuytren's contracture which is named after him and on which he first operated in 1831 and published—in ''The Lancet'', in 1834. Birth and education Guillaume Dupuytren was born in the town of Pierre-Buffière in the present-day department of Haute-Vienne. He studied medicine in Paris at the newly established École de Médecine and was appointed prosector, by competition, when only eighteen years of age. His early studies were directed chiefly to anatomical pathology. In 1803 he was appointed assistant surgeon at the Hôtel-Dieu and in 1811 he became professor of operative surgery in succession to Raphael Bienvenu Sabatier. In 1816 he was appointed to the Read chair of clinical surgery and became head surgeon at general the Hôtel-Dieu. He held ...

René Laennec
René-Théophile-Hyacinthe Laennec (; 17 February 1781 – 13 August 1826) was a French physician and musician. His skill at carving his own wooden flutes led him to invent the stethoscope in 1816, while working at the Hôpital Necker. He pioneered its use in diagnosing various chest conditions. He became a lecturer at the Collège de France in 1822 and professor of medicine in 1823. His final appointments were that of head of the medical clinic at the Hôpital de la Charité and professor at the Collège de France. He went into a coma and subsequently died of tuberculosis on August 13, 1826 at age 45. Early life Laennec was born in Quimper (Brittany). His mother died of tuberculosis when he was five years old, and he went to live with his great-uncle the Abbé Laennec (a priest). As a child, Laennec became ill with lassitude and repeated instances of pyrexia. Laennec was also thought to have asthma. At the age of twelve, he proceeded to Nantes, where his uncle, ...
