By mapping every synapse in the brain, researchers hope to create a "connectome" -- a diagram that would elucidate the brain's activity at a level of detail far outstripping today's most advanced brain-monitoring tools like fMRI.
"You're going to see things you didn't expect," said Jeff Lichtman, a Harvard professor of molecular and cellular biology. "It gives us an opportunity to witness this vast complicated universe that has been largely inaccessible until now."
The effort is part of a new field of scientific research called connectomics. The field is so new that the first course ever taught on it recently ended at MIT. It is to neuroscience what genomics is to genetics.
