The new nature vs nurture: are you your genome or your connectome?

Today, however, a new kid on the block named “connectomics” is ruffling feathers in many scientific circles. How do we begin to relate the brain’s immensely complicated structure to its function? What can this tell us about human nature that genetics has not? Watch as MIT neuroscientist Sebastian Seung ushers in the age of the Connectome, a complete map of the human brain, in order to advance our understanding of the human story.
