3D-printed brain implant 'could be used to treat human patients with paralysis'

Scientists are creating 3D-printed brain chips which could be used to treat nervous system conditions, including paralysis, by detecting and firing electrical signals. The chip has been developed and successfully tested on animals, and researchers are now hopeful it can be adapted for use in humans. It will also be able to connect to a computer and offer a host of next-generation medical benefits, scientists say. Linking the human brain to a computer is usually the work of science fiction writers and filmmakers, but moves are underway to make the technology a reality. Last month, Elon Musk hosted a high-profile event where he spoke about the developments with his own version of brain chip technology, Neuralink.
