Ep17 "What is consciousness?"

How do your billions of tiny brain cells build consciousness as they chatter away with electrical spikes and chemical signals?

And what does this have to do with ant hills, blue birds, or your memory of your first kiss? Join Eagleman on a journey into one of the central mysteries of neuroscience: why we have awareness.
