reporter: this doctor isn t your typical dr., an innovator. he won many awards, a whole new way to look at the brain. high tech cameras provide a stunning look at the cells and connections. images never captured before. and only possible through a scientific breakthrough. it s called clarity, and this picture shows what happens. on the left, a completely in tact brain from a house. on the right, a brain that is completely transparent. it s there, but almost invisible. after being bathed in a solution invented by the doctor and his team. it was the inability to see anything at all that was the most exciting thing. then that moment was really, i think, a transformative moment. reporter: later, you get these images through the use of
