The Brain Code: Mechanisms of Information Transfer and the Role of the Corpus Callosum : Routledge : 9781138591516 : 1138591513 : 14 Aug 2020 : Originally published in 1986, this stimulating and unorthodox book integrates the major findings of hemispheric research with the larger questions of how the brain stores and transmits information ? the ?brain code'. Norman Cook emphasizes how the two cerebral hemispheres communicate information over the corpus callosum, the largest single nerve tract of the human brain. Excitatory mechanisms are involved in the duplication of information between the hemispheres; in contrast, inhibitory mechanisms are implicated in the production of hemispheric asymmetries and, crucially, in high-level cognitive phenomena such as the right hemisphere's role in providing the ?context' within which left hemispheric verbal information is placed. These callosal mechanisms of information transfer are not only fundamental to the brain code; they are the simplest and
