BS 142 features the return of Dr. Michael Graziano, who first appeared on Brain Science in BSP 108. In this episode we talk about his new book, The Spaces Between Us: A Story of Neuroscience, Evolution, and Human Nature. This is an exploration of peripersonal neurons. We explore not just how they were discovered, but why they are so important in our daily lives, affecting everything from tool use to getting along with others.
