Jean-Martin Charcot´s medical instruments: Electrotherapeutic devices in La Leçon Clinique à la Salpêtrière.

In the famous painting La Leçon Clinique à la Salpêtrière (A Clinical Lesson at the Salpêtrière) by André Brouillet (1857-1914), the neurologist Jean-Martin Charcot (1825-1893) is shown delivering a clinical lecture in front of a large audience. A hysterical patient, Marie Wittman (known as "Blanche"; 1859-1912) is leaning against Charcot's pupil, Joseph Babinski (1857-1932). Lying on the table close to Charcot are some medical instruments, traditionally identified as a Duchenne electrotherapy apparatus and a reflex hammer. A closer look at these objects reveals that they should be identified instead as a Du Bois-Reymond apparatus with a Grenet cell (bichromate cell) battery and its electrodes. These objects reflect the widespread practice of electrotherapeutic faradization at the Salpêtrière. Furthermore, they allow us to understand the moment depicted in the painting: contrary to what is sometimes claimed, Blanche has not been represented during a hysterical attack, but during a moment of hypnotically induced lethargy.

"The Cabinet of Dr. Caligari": The Scientific Debate on Hypnosis and Its Legal Implications between the 19th and the 20th Century.

Movies could provide unexpected information on the state of medical knowledge in different historical periods. The first centenary of the German silent horror movie Das Cabinet des Dr. Caligari (The Cabinet of Dr. Caligari) by Robert Wiene (1873-1938) could be a timely occasion to reflect on the scientific debate of hypnosis and its legal implications between the 19th and the 20th century. In particular, this article describes the positions of the School of Salpêtrière (Charcot) and the School of Nancy (Bernheim) on the possibility of crimes committed by subjects under hypnosis and the influence of these theories on medical community and public opinion of Germany in the interwar period.

[Jean-Martin Charcot, discovery and nomenclature of amyotrophic lateral sclerosis].

In the 19th century, neurologists discovered a series of diseases characterized by limb weakness and muscle atrophy, but it was not certain whether they were variants of the same disease or completely different diseases. In 1869, Jean-Martin Charcot first diagnosed the disease, and began to use the term "amyotrophic lateral sclerosis" in 1874. The disease is also known as "Lou Gehrig's disease" in the United States, "Charcot's disease" in France, and "Motor Neuron Disease (MND)" in UK. In China, it is commonly known as "Jian-Dong Ren disease" .

Jean-Martin Charcot's influence on career of Sigmund Freud, and the influence of this meeting for the brazilian medicine / Influência de Jean-Martin Charcot na carreira de Sigmund Freud, e a influência desse encontro para a medicina brasileira

Background - Jean-Martin Charcot had a profound influence on Sigmund Freud's life and career. The founders of Brazilian neurology and psychiatry were influenced by the ideas of Charcot and Freud. Objective - To describe Charcot's influence on Freud, and both on the beginning of Brazilian Neurology and Psychiatry. Results - After Freud's stay in Charcot's neurology service during the winter of 1885-1886, there was a shift in his interest from general neurology to hysteria, hypnosis and other psychological issues, which greatly influenced the development of psychoanalytic theory. Like Charcot, Freud would become an admirer of the arts, literature, and culture. When Freud began his collection, in the late 1890s, Charcot served as an important model. In Salpêtrière Hospital, Charcot was staging a show different from modernity, capable of inspiring Freud. Antonio Austregesilo founded the first Brazilian school of Neurology, in Rio de Janeiro, inspired in Charcot. Austresegilo also practiced psychiatry, and, together Juliano Moreira and others, is considered propagator of Freud's ideas in Brazil. Conclusion - The ideas of Charcot and Freud were fundamental in the formation of physicians who helped to found and to consolidate the Brazilian neurology and psychiatry.(AU)
