Roland Piquepaille writes "Researchers at the University of Florida (UF) have developed chips which someday might be inserted in the brains of people affected by epilepsy or who have lost a limb. These neuroprosthetic chips 'can interpret signals in the brain and stimulate neurons to perform correctly.' The University claims this is the future of medicine. This is maybe a little bit extreme. Just the same, the researchers are already studying these chips with rats and hope to have a prototype ready within 4 years that could be tested on humans."
