A neuronal signal mapping method between the brain of a rat and a computer has been developed and applied to implement a 2D encoding-based real-time brain-computer interface system. The system transformed real-time neuronal activities from a prefrontal cortex, a non-motor area of a rat into control commands, which were used to drive a water disc in 2D space. The system was successfully implemented for a real-time operation based on the subject's motor intentions derived from a non-motor area, which showed a possibility of universal access to computers by removing withdraw restrictions on the motor-related region of the brain.
