Tesla CEO Elon Musk revealed the latest progress of the first human subject of its brain-computer interface company neuralink at a recent live event, saying that it "appears to be completely ** and there are no adverse reactions as we know of them." Subjects only need to think to move the mouse around the computer screen."

He also said that at the moment Neuralink is trying to get subjects to click as many mouse buttons as possible, adding that the new brain-computer interface "can control your phone or computer just by thinking and use them to control almost any device." The initial users will be those who have lost their limbs. Imagine if Stephen Hawking could communicate faster than a typist or auctioneer. That's what we're aiming for. ”

It is understood that the core of brain-computer interface lies in the establishment of a new communication and control technology between the human or animal brain and computers or other electronic devices that does not depend on peripheral nerves or muscle tissue, mainly according to the communication technology path atmosphere "non-invasive (extra-brain)", "invasive" and "semi-invasive".

At present, the non-invasive brain-computer interface has been able to use the mind to control the mouse, speller, robotic arm, drone and other operations, but the operation accuracy, information transmission rate and other aspects need to be improved, especially in multi-tasking, there will be problems such as insufficient time sensitivity and information overload, which is also very troublesome to use, and is also easy to be disturbed by noise and error.

In contrast, invasive brain-computer interfaces are better than motors that directly contact human brain neurons, reflecting and controlling them more quickly and accurately, but they are also riskier to operate. It has been previously reported that a large number of monkeys who conducted invasive brain-computer interface experiments for neuralink died after surgery, and some of them pressed their heads to the ground for no reason after implantation surgery, which made many netizens express concern about this technology.

However, Neuralink responded that the death of the monkey was not directly related to the brain-computer interface surgery, and this year's surgery did not use the traditional array of rigid electrodes, and it is understood that the Neuralink brain-computer interface uses flexible electrodes to implant the circular component into the skull layer under the **, which is not conspicuous from the outside after implantation, and can also reduce trauma to brain tissue, reduce inflammation and scar hyperplasia.

I have to say that if the neuralink brain-computer interface develops smoothly, it will be very helpful for physical disabilities, ALS, Parkinson's and other diseases, and it is worth looking forward to. However, in any case, it is clear that there are still many risks in terms of safety of this technology, and the development of this technology will still depend on the subsequent recovery of the patient.
