Some of the most exciting endeavors in neuroscience right now are trying to move beyond reductionism. The Blue Brain Project, for example, a collaboration between the École Polytechnique Fédérale in Lausanne, Switzerland, and IBM, is in the process of constructing a biologically accurate model of the brain that can be used to simulate experience on a supercomputer. Henry Markram, the leader of the project, recently told me that he's convinced "reductionism peaked five years ago." While Markram is quick to add that the reductionism program isn't complete -- "There is still so much that we don't know about the brain," he says -- he's trying to solve a harder problem, which is figuring out how all these cellular details connect together. "The Blue Brain Project" he says, "is about showing people the whole." In other words, Markram wants to hear the music.
One day, we'll look back at the history of neuroscience and realize that reductionism was just the first phase. Each year, tens of thousands of neuroscience papers are published in scientific journals. The field is introduced to countless new acronyms, pathways and proteins. At a certain point, however, all of this detail starts to have diminishing returns. After all, the real paradox of the brain is why it feels like more than the sum of its parts. How does our pale gray matter become the Technicolor cinema of consciousness? What transforms the water of the brain into the wine of the mind? Where does the self come from?
Reductionism can't answer these questions. According to the facts of neuroscience, your head contains 100 billion electrical cells, but not one of them is you, or knows you or cares about you. In fact, you don't even exist. You are simply an elaborate cognitive illusion, an "epiphenomenon" of the cortex. Our mystery is denied.
