title: [From muscle to action--Hermann von Helmholtz (1821-1894)].
abstract: Helmholtz is one of the most brilliant physiologists of the 19th century. His experimental research was respectful for strict empiricism and physical laws, but he admitted that a physiological theory of perception was only possible in the frame of a psychological approach, irreductible to physiology. He is considered as a precursor of the Neurosciences.
