Brain signals control robot

In 1999, the first demonstration of brain signals from live rat directly controlling a robot arm was published by Nature Neuroscience. The research was hailed as a breakthrough by other scientists working to combine computing with biology. Researchers from MCP Hahnemann University medical school and Duke University taught laboratory rats to operate a water-dispensing robot by thought alone. Their aim is to restore movement to patients who are paralyzed or have had limbs amputated. At first, the robot was controlled by the rat pressing a lever and researchers identified the corresponding brain activity. Then the robot was linked to a computer interpreting the rats' brain signals. The rats gained water merely by thinking about pawing the lever.
