Allometry, Brain Size, Cortical Surface, and Convolutedness

  • Harry J. Jerison


The size of the mammalian brain may be directly and closely related to the amount of information that the brain can handle. My purpose is to show how and why I think this is the case and to apply the results to comparisons among primates. Two measures of size are emphasized here: the gross weight of the undissected brain and the total surface area of the cerebral cortex. A third measure, the convolutedness, or extent of fissurization, is closely related to the first two measures.
