Is your personality written into the circuitry of your brain? With brain disease, can someone lose who they are without realizing it? What happens when the person changing is the only one who can't see it? What does it mean to love someone whose personality has become unrecognizable? If you carried a genetic mutation that would alter your brain in the near future, would you want to know? Join Eagleman with bestselling author Robert Kolker to discuss these questions in the context of his new book about frontotemporal dementia, The Vanishing Family.

How do you get trillions of cells to collaborate as the single organism that we call you? Does that kind of cooperation create opportunities for hijacking -- for example, is cancer a form of "cellular cheating"? Can we take the lessons learned from biology and apply them to understanding politics? And what do models of cooperation tell us about building and living with AI? Join Eagleman with evolutionary biologist and cooperation theorist Athena Aktipis to understand cooperation and competition from cells to societies to our technological future.

Why do brains dream, and why are dreams so bizarre? Why doesn't your clock work in your dreams? And even though you spend much of your working day looking at your cell phone and computer – why do they almost never make appearances in your dream content? Is dream content the same across cultures and across time? Are dreams experienced in black & white, or in color? Are dreams the strange love child of brain plasticity and the rotation of the planet? What is the relationship between schizophrenia and dreaming? In the future, will we be able to read out the content of somebody's dream? Join Eagleman this week to learn why and how we spend a fraction of our sleep time locked in different realities, swimming in plots which aren't real but which compel us entirely nonetheless.
