The voice helps us connect with others, forge bonds, and foster relationships. But the voice also creates connections inside our own body and, in particular, shares an ancestral bond with our hands. Dr. Rébecca Kleinberger reveals the many strings that tie hands and voice together from fine dexterity, memory, motor cortex, and the origin of language. Throughout this journey, we explore questions such as: do animals have a dominant hand? What do weightlifters, babies, and salamanders have in common? Or what does the inner voice of deaf people feels like? And how we can use our voice to touch people.
