When  President Obama on Tuesday highlighted 19 executive actions he says he  is taking to improve the mental health of U.S. troops and veterans, one  of them centered on a particularly novel effort: The development of new  computer chips designed to modulate the nervous system to help with  everything from arthritis to post-traumatic stress.
 
 The project is headed by the Defense Advanced Research Projects  Agency, a Pentagon agency that develops a variety of high-tech equipment  for the U.S. military. It’s known as the Electrical Prescriptions  program, or ElectRx (pronounced “electrics”). Program officials say the  goal is to develop a technology that could help people heal more quickly  through the use of biosensors and electromagnetic devices that control  human organs.
 
 “Instead of relying only on medication, we envision a closed-loop  system that would work in concept like a tiny, intelligent pacemaker,”  said Doug Weber, the program’s manager. “It would continually assess  conditions and provide stimulus patterns tailored to help maintain  healthy organ function, helping patients get healthy and stay healthy  using their body’s own systems.”
 
 Obama did not reference the new program directly in his speech  Tuesday at the American Legion national convention in Charlotte, N.C.   In a joint fact sheet released by the Pentagon and the Department of  Veterans Affairs, however, the agencies said DARPA will start a new  $78.9 million, five-year research program “to develop new, minimally  invasive neurotechnologies that will increase the ability of the body  and brain to induce healing.” It’s part of the Obama administration’s  larger “BRAIN Initiative,” which involves the National Institutes of  Health, DARPA, the National Science Foundation and the Food and Drug  Administration, among other organizations.
 
 Officials say the BRAIN Initiative — which stands for Brain  Research through Advancing Innovative Neurotechnologies — includes a  related DARPA effort to build new brain chips that will be able to  predict moods to help treat post-traumatic stress. It’s known as the  SUBNETS program, short for Systems-Based Neurotechnology for Emerging  Therapies. Teams at both the University of California, San Francisco,  and Massachusetts General Hospital in Boston are involved.
 
 The major hurdle for the ElectRX program may be shrinking the  technology needed so that it can be used in the body. Implantable  devices already are in use to fight inflammatory diseases and other  health problems, but most are about the size of a deck of cards,  requiring surgical implantation that can result in side effects, DARPA  officials said. They want “ultraminiaturized devices” that would could  be inserted through needle injection or other less invasive means.
