This is a show about your brain and how it perceives motion. Evolving in a world that is constantly moving, the human brain had to develop a pretty sophisticated sense of motion in order to survive. This episode stops to ask some deceptively simple questions-What really is motion? Is the movement that you see real? Or is the wiring of your brain's motion detectors merely being fooled? We explore the science behind how your brain detects and interprets motion, and you'll see how easily this hard-wiring can be fooled... for better and for worse.
