David Linden: Touch: The Science of Hand, Heart, and Mind

"The sensation of touch is vital to nearly every aspect of the human experience. The way our bodies’ touch circuits are organized affects everything we do from making choices about what to buy, using language and how we experience both pleasure and pain. Johns Hopkins University neuroscientist David Linden explains how the biology works and the different brain systems that process this key sensation. He’ll also explain why context is critical when it comes to touch — from skin to nerves to brain — and why touch is crucial to our sense of self and our experience of the world."
