Brain Science Podcast #22 is an interview with Dr. Christof Koch of Cal Tech, one of the pioneers in the neurobiological study of consciousness.  About two decades ago, when Koch and Francis Crick began looking for what they called the neural correlates of consciousness (NCC), such a quest was considered controversial; but now the field is increasing in popularity.  In our interview, we talked a little about his book,The Quest for Consciousness, as well as his on-going research and his thoughts about what the future might bring.
