Understanding the brain

We don't yet know how the brain gives us our awareness of being alive. "But", says professor Susan Greenfield of Oxford University, "in 50 years' time we may have a clearer idea of how the brain generates consiousness". Studies of the brain and the nature of consciousness will bring much greater understanding of disorders such as schizophrenia and depression. This knowledge will help reduce suicide rates, one of the major causes of death worldwide. Other scientists go further than Professor Greenfield. They believe that by 2060 computers will develop their own consciousness and emotions. Human beings may eventually be replaced by computers in some areas of life.
