A biological neural network drives a robotic actuator

.Abstract. During the past three years our group experimented the growth of networks of human neural stem cells on a MEA (Microelectrode Array) support. The neurons were stimulated by digital patterns and the output signals were analysed . In previous experiments, the neurons replied selectively to different patterns and showed similar reactions in front of the presentation of identical or similar patterns. Analyses performed with a novel Artificial Neural Network called ITSOM showed the possibility to decode the neural responses to different patterns. In the described experiment, the neurons are connected to a robotic actuator: simulated perceptions stimulate the neurons, that react with organized electric signals. The signals are decoded by the Artificial Neural Network, that drives a minirobot.
