One of the most influential characteristics of modern humans is our sophisticated social brains, but how can we ethically study the human condition in situations where the social aspect is impacted? Previous studies done on post-mortem tissue samples are being phased out in favor of a futuristic new method--the brain in a dish. Learn how one doctor has pioneered a scientific method to grow brain organoids in a petri dish that spontaneously generate complex brain waves, and how the International Space Station plays a critical role in the study of autism spectrum disorder, Alzheimer's and astronaut health.
