The world’s first brain prosthesis – an artificial hippocampus – is about to be tested in California. Unlike devices like cochlear implants, which merely stimulate brain activity, this silicon chip implant will perform the same processes as the damaged part of the brain it is replacing. | The prosthesis will first be tested on tissue from rats’ brains, and then on live animals. If all goes well, it will then be tested as a way to help people who have suffered brain damage due to stroke, epilepsy or Alzheimer’s disease.” Duncan Graham-Rowe —World’s First Brain Prosthesis Revealed New Scientist)
