a hand holding a film-like brain implant Credit: Precision Neuroscience A startup founded by a former Neuralink exec is developing a safer, easier-to-place brain implant — and it just tested the device in people for the first time. Brain implants: Almost everything you think and do comes down to tiny pulses of electricity zipping between the 120 billion neurons in your brain. Brain implants give us a way to see this activity with far more precision than any device outside of the skull, like an EEG or MRI. By pairing this brain implant data with advanced computer algorithms, researchers have...
