Why does the simple act of raising your coffee mug to take a sip involve more computation than a supercomputer can do? Why do robots move, well, robotically? Join neuroscientist Sam Pfaff as he explains the answers to the these questions as well as describing the flashy neurological circuits—called "circuitoids"—his lab builds from stem cells to study repetitive actions like walking—and how that work might provide insights into degenerative motor diseases like ALS.
