With nano-probes, scanning machines and electromagnetic devices, we can now see precisely what is happening in the brain during mental operations. These brain functions can be recorded, analyzed, decoded and stored on digital devices (e.g., computers). They may then be played back into other electronic circuitry or another person’s brain. These technological innovations are leading to exciting applications, such as brain-controlled artificial legs and arms, whole body exoskeletons and “intelligent” robots. The history of brain research will be reviewed and current finding presented.
