The working relationship between the Vogts and Brodmann (1868-1918) was compromised after the Vogts published their first results on their electrical excitability of cortical regions in 1907, without listing him as a coauthor. In this paper the different areas in the brain were characterized with the electrical stimulation that had been entirely done by the Vogts. Brodmann, who had begun his work on the comparative ‘cytoarchitectonic subdivision’ of the cerebral cortex in mammals and humans in 1903 while working at Neurobiological Laboratory, published his findings in 1907, and they remain the basis for anatomical maps of the cortex and its division into areas even today. Moreover, despite substantial discrepancies, the Vogts’ work on electrical stimulation validated the areas identified by Brodmann as functional units of the cortex.
