This paper focuses on the make-up of different cultures in experimental neurology, neuroanatomy, and clinical psychiatry. These cultures served as important research bases for early regenerative concepts and projects in the area of neurology and psychiatry at the beginning of the 20th century. Nevertheless, the developments in brain research and clinical neurology cannot be regarded to be isolated from broader societal developments, as the discourses on social de- and regeneration, neurasthenia, nerve-weakness and experiences of the brain-injured after WWI show. Societal (...) and cultural developments directly influenced researchers’ conceptualisation, scientific ideas, and even their experimental and clinical orientation. They directly reflect which scientific problems the neuroscientists felt inclined to address and what areas they began to leave aside. Using the concept of socio-technical experiments, it is demonstrated that research methodologies in neuronal de- and regeneration studies were not simply a product of recent advances in the scientific differentiation of somatic neurology or brain-psychiatry. Moreover, they resulted in important interdisciplinary attempts which emerged from great collaborative work including neuroscientists from various areas of investigation in both basic and clinical contexts.
