From brain cytoarchitectonics to clinical neurology: Polish Institute for Brain Research in Vilnius, 1931-1938.

The Polish Institute for Brain Research was established in Warsaw in 1928 to support scientific research on the brain and its functions. The director of the institute was Maksymilian Rose (1883-1937), a distinguished Polish neurologist and neuroanatomist, a disciple of Oskar Vogt and Korbinian Brodmann. In 1931, the Institute was moved from Warsaw to Vilnius. The Institute was well-known in Europe at the time because of the research in the fields of neuroscience, clinical neurology, and psychiatry, as well as the cytoarchitectonic analysis of social activists' brains-a fashionable, neophrenological way to link the mental functions of deceased geniuses with the cellular composition of their central nervous systems. In 1939, the work of the Institute was interrupted by World War II; some of the preparations and materials were moved from Vilnius to Warsaw, some were stored in Vilnius, and some were lost. In this article, we analyze the primary and secondary sources, some of which were obscure for over 80 years, and evaluate the most important scientific achievements of the Polish Institute for Brain Research, as well as its legacy in the early period of modern neuroscience and neurology in interwar Vilnius.
