The Brain Code


The many puzzles about the human mind need to be explained on the basis of the unusual features of the human brain. Brain size, the relative size of association cortex, and the unusual properties of the hands and organs of speech certainly need to be considered, but what is most firmly established in clinical neuropsychology is the fact that the two cerebral hemispheres of the human brain have slightly different functions. Discussion of this issue can be found in the following papers:


Behavioral Science (1984), Interdisciplinary Science Review (1988), New Ideas in Psychology (1989), and Consciousness and Cognition (1999)


The basic outline of the story of the lateralized specialization of the cerebral hemispheres was already known by the 19th century, and became a major theme in both clinical and popular neuropsychology in the 1980s. The implications of hemispheric specialization for normal psychology and psychopathology remain to be fully understood. Many hypotheses have appeared as articles and monographs (my own views were summarized in The Brain Code: Mechanisms of information transfer and the role of the corpus callosum. (Download Chapt1, Chapt2, Chapt3, Chapt4, Chapt5, Chapt6, Chapt7, Chapt8, Appendix), Methuen, London, 1986, and in a more recent volume, Tone of Voice and Mind, Benjamins, Amsterdam, 2002).
