ABSTRACT
This chapter analyses the four fields of an electrotechnical mobilization of body, mind, and soul during the interwar period: Representation techniques in which electrotechnical apparatus and graphical methods created mobile representations of organic as well as psychic phenomena; design techniques to make a neurotechnics merge bodily functions with machines; communication techniques, taking the contemporary debate about brainwaves and telepathetic communication as an example; and manipulation techniques that, during the Weimar Republic, led to material switchings between human and electrotechnology, for example, high-frequency therapies according to d’Arsonval or radio-wave treatment. The electrotechnics of the live mind of the Weimar Republic mirror a continual experimentation with apparatus and concepts in ever newer arrangements. In the popular discourses on the electrotechnics of the live mind, the electrical brain experienced its first boom before electrophysiological research and electroencephalography would stabilize the electrical brain as an epistemic thing.
