Mind in motion.

The article discusses neuroprosthetic technologies which use brain waves to control and manipulate computer cursors and robotic limbs as of September 2012. Topics include how neuroscientist Miguel A. L. Nicolelis and his colleagues plan to develop an exoskeleton to be worn and controlled by a paraplegic at the 2014 World Cup, and how bioelectrical engineering created signals connecting the rindlike cortex of the brain to computer systems. Additional information is presented on how the exoskeleton will operate using electrodes implanted in the motor cortex. INSET: The Long Road to Brain-Controlled Prosthetics.
