Elon Musk said the patient was recovering well and the initial results were "promising."

Neuralink co-founder and owner Elon Musk said a computer chip developed by Neuralink has been implanted in its first human test subject, marking a milestone as brain-computer interface (BCI) research enters the forefront.

"The first person to receive a Neuralink implant yesterday is recovering well and preliminary results show promising neuron spike detection," Musk announced on Twitter late Monday.

Neuralink's first foray into BCI aims to be able to decode intended motion signals from brain activity to control external devices such as computers. Since then, Musk has also laid out his vision for the company's first product: telepathy.

He wrote on Twitter: "It can control your phone or computer and control almost any device through them, just think, the first users of it will be those who have lost limbs. Imagine being like Stephen "Hawking was able to communicate faster than a typist or an auctioneer. However, that's the goal."

The California-based company, founded in 2016, received approval from the federal regulator the Food and Drug Administration in September to begin human trials. Neuralink is openly soliciting volunteers to participate in its PRIME study, which stands for "Precision Machine Implantation in Brain-Computer Interfaces."

Discussion of the company's progress moderated in November, however, when a Reuters report detailed painful and sometimes bizarre results from the company's testing on animals.

Volunteer pool

While no further details were provided about Sunday's program or its subject matter (the Neuralink company blog was last updated nearly five months ago), Neuralink's recruitment materials outline some of the requirements for participating in its human trials.

"We are looking for people who have quadriplegia due to spinal cord injury or amyotrophic lateral sclerosis (ALS) and who have shown no improvement for at least a year since the injury," the company explained in a statement, which was also posted online. Participants must also be 22 years or older and have a consistent and reliable caregiver.

The time commitment included nine visits over 18 months (some in clinic, some at home), and two one-hour "study sessions" per week.

Even after the initial study is completed, Neuralink hopes to keep participants with them for five years and 20 additional visits.

Science & Technology

The research test has several components, including the BCI implant itself (called the N1 implant), and an implant that will "surgically place the N1 chip in the area of ​​the brain that controls motor intention."

Neuralink says the N1 has 1,024 electrodes spread across 64 wires, "each of which is thinner than a human hair," and it can record neural activity and transmit it to a mobile app, with the goal of enabling patients to use it. Your own thoughts control the computer.

Neuralink says the implant is "invisible in appearance."

extremely controversial

BCI technology is being developed by many research institutions and private companies. However, few of these involve surgical implantation.

Animal rights group Physicians Committee for Responsible Medicine (PCRM) has long condemned Neuralink's practices.

"Implantable devices like Neuralink have numerous problems, including being difficult to repair and having a high potential for serious medical complications for patients," the group claimed. The group claimed the company violated federal animal welfare laws but was granted the A "free pass". From the agency responsible for law enforcement. "

When images of Neuralink's animal testing subjects were released in November, PCRM said the company was "mutilating and killing monkeys" citing "chronic infections, paralysis, epilepsy and death." The group urges Neuralink to stop its animal testing and instead focus on improving non-invasive brain-computer interfaces.

"Non-invasive [brain-computer interfaces] can monitor large-scale neuronal activity throughout the brain without risk," the organization said, adding that in addition to aiding movement and movement, they have It can "allow people to communicate directly using computers."

Last fall, scientists were able to use skin-surface electrodes to reproduce the music that subjects were thinking about.

However, Neuralink's surgical approach is not unique.

Last summer, a neural implant helped a paralyzed New York man move his arm and feel touch.

Houston-based Motif Neurotech, which is developing "minimally invasive" wireless therapy hardware for mental health, announced an $18.75 Series A round last week.

Motif Neurotech CEO Jacob Robinson told reporters that Neuralink's rapid progress in human testing "confirms the interest and demand for neurotechnology." #Neuralink #内容挖矿
