Sebastian Seung, MIT professor of computational neuroscience and of physics, is among the cutting-edge researchers undertaking the monumental task of mapping the brain's connections. Seung believes that the biological basis for identity lies in the connectome: the pattern of connections between the brain's neurons, which change slowly over time as people learn and grow. This, he says, is where genetic inheritance intersects with life experience.

On April 4, 2012, Seung offered his thoughts on the brain's wiring and how it influences personality and answered questions from the worldwide MIT alumni community. Watch the video then join the discussion online.
