Summary
The first invasive brain chip that Neuralink embedded into a human brain has malfunctioned. The neuron-surveilling threads appear to have become dislodged from the participant's brain. It's unclear what caused the threads to become "retracted" from the brain.
The changes were made to the device to make it more responsive. The changes were also made to make the device easier to use. The new device is called the "Naked" and it is made of a special material. It is made up of a series of small pieces of metal.
