How rat brain neurons control a flight simulator

• Getting rat brain neurons to control a flight simulator
  • "You want to know how the brain does what it does, how it computes," DeMarse says in his lab, between sips of office-brewed Starbucks. "The more you know about that, the more you can apply that information to real-world problems ... especially diseases."
  • There is no wire-rigged brain, pulsing in a bowl.... Instead, there are about 25,000 rat neurons - or brain cells - thriving in a glass tray the size of an eyeglass lens. Considering the human brain has billions of neurons, 25,000 doesn't add up to much. Picture grains of sand sprinkled in water.... The neurons are nourished weekly, and almost immediately begin to extend weblike strands to connect with each other.
