kkleiner (1468647) writes "Kevin Warwick, once a cyborg and still a researcher in cybernetics at the University of Reading, has been working on creating biological neural networks that can control machines. He and his team have taken the brain cells from rats, cultured them, and used them as the guidance control circuit for simple wheeled robots. Electrical impulses from the bot enter the batch of neurons, and responses from the cells are turned into commands for the device. The cells can form new connections, making the system a true learning machine."
