Robert and Carl Zimmer teamed up tonight to moderate a brain mapping brouhaha live at Columbia University. The subject: does the brain's wiring make us who we are? The event has ended, but thanks to everyone who tuned in for the live webcast (and the lively web chat archived below).

Tonight's debate was the second annual event presented by Neuwrite. Leading neuroscientists Sebastian Seung (Professor of Computational Neuroscience, MIT, and 
author of Connectome: How the Brain’s Wiring
 Makes Us Who We Are) and Anthony Movshon (Professor and Director, 
Center for Neural Science, NYU) went head to head on one of their field's hottest topics. Thanks to everyone who tuned in and joined us for the web chat (which is closed now, but archived below).
