Brown-Séquard, a restless mind.

Brown-Séquard, a remarkable medical personality of the 19 th century, was born in a small island of the Indian Ocean. He travelled over the world exerting his skills: a successful physician, and an innovative researcher, with a very ample range of interests. His favored subject was the nervous system. The spinal cord was studied extensively, with novel and important discoveries on the sensory pathways. He identified cases with spinal cord hemisection, and described the clinical presentation corresponding to a syndrome which bears his name (Brown-Séquard syndrome), for which he is best known among neurologists. Regarding the brain, he proposed nine mental and physical functions (organs) related to dynamically interconnected cell clusters, in harmony with the " réseau de cellules anastomosées ", " activités dynamogeniques et inhibitrices ", and " action à distance " concepts. Finally, he is considered by some as the "father" of endocrinology, due to his studies on glands and their secretions.

Brown-Séquard, notável personalidade médica do século 19, nasceu em uma pequena ilha do Oceano Índico. Viajou pelo mundo exercendo suas habilidades: médico de sucesso e pesquisador ousado, com gama muito extensa de interesses. Seu assunto favorito era o sistema nervoso. A medula foi estudada de modo amplo, com descobertas novas e importantes sobre as vias sensitivas. Identificou casos com hemisseção medular e descreveu o quadro clínico correspondente a uma síndrome que leva seu nome (síndrome de Brown-Séquard), motivo pelo qual é melhor conhecido entre os neurologistas. Considerando o cérebro, propôs nove funções (órgãos) mentais e físicas relacionadas de modo dinâmico a conglomerados celulares, em harmonia com seus conceitos de “ réseau de cellules anastomosées ”, “ activités dynamogeniques et inhibitrices ” e “ action à distance ”. Finalmente, ele é considerado por alguns como “pai” da endocrinologia, devido seus estudos sobre glândulas e suas secreções.

Brown-Séquard, pesquisador e médico, foi uma das mais extraordinárias personalidades do século XIX. Nascido em uma pequena ilha no meio do Oceano Índico, viajou pelo mundo exercendo suas habilidades de médico respeitável, além de pesquisador inovador, experimental e clínico. Seus interesses eram amplos, principalmente na área da neurologia. A medula foi estudada durante décadas, dando inicialmente lugar à sua tese de doutorado. Esses estudos levaram à descrição de uma síndrome devida à hemisseção da medula, que traz seu nome e é um dos seus feitos mais conhecidos entre os neurologistas. Outros variados assuntos levaram à produção de grande número de trabalhos, publicados em livros e periódicos reconhecidos.

Brown-Séquard, researcher and physician, was one of the most amazingpersonality of the 19th century. Born in a small island in the middleof the Indian Ocean, he travelled over the world exerting his skills of a reputable physician and an innovative experimental and clinical researcher. His interests were ample, mainly in the neurological area. The spinal cord was studied for many decades, ensuing initially his doctorate thesis. These studies led to a description of a syndrome due to hemisection of the cord, that bear his name, one of his most known feat among neurologists. Other varied subjects led to the production of a large number of works, published in books and renowned journals.
