Haim Harari, President of the Weizmann Institute of Science, noted that "the world of computers, information systems, electronics and optics is now dominating every aspect of our lives" (4, p. 3). He also highlighted the advances in genetics that influence our health, our food, and our behavior. The Human Genome Project already is affecting our theories. The third advance that Professor Harari underlined is our increasing understanding of the brain and its relationship to brain imaging and other functional aspects of the central nervous system (CNS). These and other "revolutions" are affecting research, theory, and treatment. Gradually we are replacing "old scientific fields with new ones, enhancing our facilities" (4, p. 3), and launching new scientific and clinical adventures.
