Oskar Vogt

1870–1959 · German neurologist and pioneer of cortical cytoarchitecture

Share:FacebookWhatsApp

Oskar Vogt (Husum, 1870 - Freiburg im Breisgau, 1959) was a German neurologist who trained in medicine at Kiel and Jena, where he earned his doctorate in 1894. Together with his wife, the French neurologist Cécile Vogt-Mugnier, he became a central figure in the anatomical study of the brain in the twentieth century. He is sometimes also described as a physicist, but his name is chiefly linked to brain research.

In Berlin, in 1898, the couple founded the Neurologische Zentralstation, which in time grew into the Kaiser Wilhelm Institute for Brain Research, where Vogt served as director. Their cytoarchitectonic studies of the cortex proposed a six-layer pattern and distinguished iso- from allocortex. They also worked on the thalamus and the striatum. Vogt was additionally an entomologist, with a particular interest in bumblebees. He was dismissed from his post in 1936, having opposed the Nazi regime.

His interest in locating the origins of talent in the brain led him to examine Lenin's brain after the leader's death, where he found unusually large pyramidal cells, which he read as a sign of superior capacity. In 1925 he accepted an invitation from Moscow to set up a brain research institute. His influence reached students such as Korbinian Brodmann and Rafael Lorente de Nó, and the institute he helped build gave rise in 1945 to the Max Planck Institute for Brain Research.

Key ideas

  • Cytoarchitecture: the study of the cellular organization of the cortex as a basis for understanding its areas and functions.
  • Iso- and allocortex: the distinction between these two cortical zones, proposed by the Vogts to classify the brain.
  • Six-layer pattern: their proposal of a six-layered cortical structure, in contrast with the models of Meynert and Cajal.
  • Localization of function: the idea that certain mental capacities may be linked to specific anatomical features of the brain.

Curiosities

One slice of Lenin

After Lenin's death, Vogt took home to Berlin a single 20-micrometre slice of the brain, one of 30,953 into which it had been cut.

A large bumblebee collection

His entomological collections, about 400,000 specimens including some 300,000 bumblebees, are kept at the Zoological Museum in Amsterdam.
