Sentience

by Daniel Toker

What is a mind? What does it mean to be conscious? And why do the answers matter? Hosted by neuroscientist Daniel Toker, PhD (@the_brain_scientist), Sentience explores the biggest questions about minds, intelligence, and what it means to be a thinking, feeling being. Through conversations with scientists, philosophers, physicians, historians, entrepreneurs, and other leading thinkers, each episode uncovers ideas that could change how we understand ourselves—and our future.
