Music is perhaps the most the sublime gift of hearing. But why is music so important to us and why does it have such a profound effect on the human heart? In this episode of The Science of the Senses, finding the answer to that question will take us on a journey through the ear, into the brain and right into the heart of the human psyche. Along the way, we will meet world class neuroscientists, like Daniel Levitin (author of bestseller This is Your Brain on Music) and Steven Pinker (one of Time Magazine's 100 most influential people), and a host of extraordinary people — from a woman whose brain cannot "hear" music to a deaf musician who is one of the world's top percussionists.

We'll also meet Dr. Blake Papsin, of Sick Children's Hospital in Toronto, to explore how a revolutionary little device called the cochlear implant is restoring hearing to the deaf.
