A Florida scientist has trained a brain consisting of cultured rat cells to fly a simulated F-22 fighter jet. [Insert "I, for one, welcome our new rat brain pilot overlords" joke here.]
To control the simulated aircraft, the neurons first receive information from the computer about flight conditions: whether the plane is flying straight and level or is tilted to the left or to the right. The neurons then analyze the data and respond by sending signals to the plane's controls. Those signals alter the flight path and new information is sent to the neurons, creating a feedback system.
FYI, this story is a couple of years old...if that matters to you.
