Expérimentation et clinique électroencéphalographiques entre physiologie, neurologie et psychiatrie (Suisse, 1935-1965)

The electroencephalogram (EEG), invented by the German psychiatrist Hans Berger in 1924, reached the neurophysiological laboratories and several clinical contexts in the mid-30s. In Switzerland, some skeptical physiologists and enthusiastic psychiatrists paved the way for its integration, but it was only after the Second World War that an emerging field of epileptology became part of a process of technological and epistemological innovation which raised great expectations and produced a large body of research at the crossroads of physiology, neurology and psychiatry. An informal network was created, characterized by clinical, scientific and local institutional cultures. The EEG also made it possible to detect some clinical entities, not however without transforming them, as in the case of epilepsy. Some attempts to probe psychiatric diseases and subjects with the EEG are described as negotiated relationships between clinical observations, subjective manifestations or symptoms and inscriptions of a spontaneous or elicited electrical brain activity. These attempts shape a clinical and experimental cerebral subject, which is analyzed in this article from the point of view of its technical aspects and the concrete procedures on which it depends.
