Elon Musk's company, Neuralink, implanted a wireless brain chip in a human for the first time.
The chip records brain signals and transmits them wirelessly, potentially allowing control of devices through thought.
This initial test focused on "movement intention" and could help people with paralysis communicate and control devices.
The chip is still experimental and requires further testing before widespread use.
Neuralink faces competition from other companies developing similar brain-computer interfaces.
Existing brain implants have already shown promise in helping people with communication difficulties.
