By now, controlling prosthetic limbs or video games by thoughts alone aren’t really news anymore. It sounds cool, but undergoeing surgery just for that does sound a little over the edge. But according to Wired News, that won’t even be necessary soon:
Hitachi’s new neuroimaging technique allows its operator to switch a train set on and off by thought alone, and the Japanese company aims to commercialize it within five years.
Hitachi’s system doesn’t invasively co-opt the nervous sytem, instead using a topographic modelling system to measure blood flow in the brain, translating the images into signals that are sent to the controller. So far, this new technique only allows for simple switching decisions, but Hitachi aims to commercialize it within five years for use by paralyzed patients and those undergoing “cognitive rehabilitation.”
