the_newsbeagle writes: Elon Musk has set out to change the world with SpaceX’s reusable rockets and Tesla’s electric cars, and now he plans to change your brain. His new company, Neuralink, will reportedly build delicate brain implants called “neural lace” to help people with neuropsychiatric disorders and to give healthy people strange new mental abilities. But the news announcements about the company contained scant details about what kind of hardware Neuralink might actually build, and what engineering challenges the company will have to overcome in pursuit of miniaturized and safe brain implants. Here, five neuroscience experts describe those challenges, and give hints on what to expect from Musk’s neural dust. One of the neuroscientists is Mary Lou Jepsen, founder of the Openwater startup, which is looking for ways to develop a noninvasive BCI for imaging and telepathy. Jepsen was also “an engineering executive at Facebook working on its Oculus virtual reality gear; before that she spent three years at Google X, running advanced projects on display technology,” reports IEEE Spectrum. She says that Neuralink will likely face many medical hurdles, even if their process doesn’t require splitting open patients’ skulls. “The approach as I understand it (not much is published) involves implanting silicon particles (so called “neural lace”) into the bloodstream. One concern is that implanting anything in the body can cause unintended consequences,” says Jepsen. “For example, even red blood cells can clog capillaries in the brain when the red blood cells are made more stiff by diseases like malaria. This clogging can reduce or even cut off the flow of oxygen to the parts of the brain. Indeed, clogging of cerebral capillaries has been shown to be a major cause of Alzheimer’s progression. Back to neural lace: One concern I would have is whether the silicon particles could lead to any clogging.”
