Computational Neuroscientist Sebastien Seung believes that understanding how our brains are connected could explain why every person is unique. Put simply, we are all wired differently. Neuroscientists have long assumed that learning is a result of making new connections in the brain, can this be extended to explain our personality and disorders of the brain such as autism and schizophrenia? To test this hypothesis Sebastien and his colleagues develop and study connectomes, comprehensive maps of neural connections in the brain. The connectome below depicts the neurons of the retina and was reconstructed by computer from 3D microscopic images.
