Neuralink: Elon Musk unveils pig with chip in its brain

Elon Musk has unveiled a pig called Gertrude with a coin-sized computer chip in her brain to demonstrate his ambitious plans to create a working brain-to-machine interface. "It's kind of like a Fitbit in your skull with tiny wires," the billionaire entrepreneur said on a webcast. His start-up Neuralink applied to launch human trials last year. The interface could allow people with neurological conditions to control phones or computers with their mind. Mr Musk argues such chips could eventually be used to help cure conditions such as dementia, Parkinson's disease and spinal cord injuries.
