A brain implant device successfully helped boost impaired capacity for thinking and decision making in rhesus monkeys, The New York Times reports. Wake Forest Baptist Medical Center and University of Southern California researchers led the study, which tested an implant that included two sensors and implanted into the cerebral cortex. While such a device is likely years away from use in humans, the NYT notes, it helps create a template for what to do to boost brain capacity in the frontal cortex, where major thinking takes place. Details are published in The Journal of Neural Engineering. Story (sub. req.)
