Elon Musk has
showed off his company Neuralink’s brain-computer interface for the first time.
In an announcement on 28 August, Neuralink unveiled prototypes of its device
and showed off pigs with the devices implanted in their brains.
The device resembles a coin with extremely thin wires coming from one side of it. It is designed to be implanted in the skull, with the wires embedded a few millimetres into the surface of the brain.
Those wires can then detect when neurons are firing, or emit their own electrical signals to make the neurons fire. Musk showed a video of neurons responding to the electrodes.
Eventually, the hope is that these small devices
will be able to both read and write neuron signals, helping with medical
problems that originate in the brain and spine and maybe even allowing humans
to integrate computers into their brains in the distant future, Musk said.
