Against the backdrop of technology giants increasingly entering the field of neuroscience, a competition on brain-computer interfaces is quietly unfolding. Unlike Elon Musk's high-profile Neuralink, a startup supported by Jeff Bezos and Bill Gates - Synchron, is emerging as a dark horse in this competition. Tom Oxley, a 44-year-old American doctor and neuroscientist, immersed himself in brain-computer interface research 12 years ago, founding Synchron. Compared to Musk's Neuralink, Synchron's devices do not require skull removal or craniotomy, but instead deliver the chip into the brain through the jugular vein, significantly reducing surgical risks and making it more acceptable to patients.
