How do the physical occurrences which take place in our brains create the world of conscious experience ? Philosophers have long disputed this question but today, it is science which is in a position to formulate real answers. Gerald M.Edelman and Giulio Tononi demonstrate that the processes which lead to consciousness are not confined to the brain, but are actually dependant on the functioning of numerous areas. They also show that these interactions are not fixed processes, but are constantly adjusted and modified. This research represents one step further towards understanding our identity and our complexity.

Gerald M.Edelman, who has received the Nobel Prize for medicine, heads the Institute of Neurosciences at La Jolla in California. Giulio Tononi is a researcher at the Institute of Neurosciences.
