Does your dog experience conscious thought? What about your neighbor? How can you be sure? This is a difficult challenge for researchers, given the need for objectivity. Neuroscientist Christof Koch explores the relationship between brains, behavior, and consciousness.

Born in the American Midwest, Christof Koch grew up in Holland, Germany, Canada, and Morocco. He studied Physics and Philosophy at the University of Tübingen in Germany and was awarded his Ph.D. in Biophysics in 1982. Following four years at MIT, Christof joined the California Institute of Technology as a Professor in Biology and Engineering. After a quarter of a century, Christof left academia to become the Chief Scientific Officer at the notforprofit Allen Institute for Brain Science in Seattle. He is leading a ten year, largescale, high throughput effort to build brain observatories to map, analyze, and understand the cerebral cortex. He loves dogs, climbing, biking in Seattle, and longdistance running.

Christof has authored more than 300 scientific papers and articles, eight patents, and five books concerned with the way neurons process information and the neuronal and computational basis of visual perception, selective attention, and consciousness. Together with his longtime collaborator, Francis Crick, Christof pioneered the scientific study of consciousness. His latest book is Consciousness—Confessions of a Romantic Reductionist.

This talk was given November 9, 2013 in Seattle at TEDxRainier, a local TEDx event, produced independently of the TED Conferences.

TEDx is a program of local, selforganized events that bring people together to share a TEDlike experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, selforganized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are selforganized.* (*Subject to certain rules and regulations)
