HOW THE IMPLANT IS PUT IN YOUR HEAD

■ Tiny implant hermetically sealed in container

■ Battery charged wirelessly

■ The chip processes brain signals and relays information to devices using Bluetooth

■ The implant records neural activity through 1,024 electrodes across 64 threads so fine they can't be inserted by hand

■ Musk says robot removes small part of skull, connects threads to brain and glues up incision. It takes less than an hour under local anaesthetic
