Functional Anatomy of Human Speech

  • J. Szentágothai
Part of the Acta Neurochirurgica Supplementum book series (NEUROCHIRURGICA, volume 56)


The outlines of an investigation into side differences between the Planum temporale (The Geschwind-Levitzky areas) of ten human brains are given. Volume of this area and cell numbers are clearly asymmetric, the left side being consequently larger by 38–34% over the same area at right. Cell density (cell No/volume) is virtually the same on both sides. Some comments upon the data are being made.
