Scientist uses a remote-controlled brain implant to control the path taken by mice. The implant alters the neural networks of the mice using wireless signals, allowing researchers to study neural stimulation. The “optofluidic” implant was developed with the hope that it could one day be used to treat a range of neurological disorders in humans. The battery-powered device is implanted in the head of the mouse and is fitted with reservoirs of drugs that are used to alter brain functions. The implant was used to make mice walk around in circles by injecting morphine into the part of the brain that controls motivation and addiction.
