fantasycrypto| Musk Brain Computer Company's first human subject suffered a brain device failure: a wiring fell off and some data was lost

Musk's road to "man-machine symbiosis" was not easy, and his brain-computer company revealed that the first human subject had a hardware problem with his internal device.

Neuralink said in a blog post on May 8 that in the weeks after the operation on Nolan Arbor in January, some of the wires embedded in the brain tissue fell off, affecting the transmission rate of information, losing some data and causing the device to not work properly.

The loss of wiring led to a drop in bits per second, which is a measure of the speed and accuracy of Abo's computer cursor controlled by his mind, Neuralink said.

Neuralink said that the electrode wire problem was fixed by modifying the recording algorithm to make it more sensitive to neural group signals and improving the technique of converting signals into cursor movement, which "resulted in rapid and continuous improvements that have replaced the initial performance of Nolan (implanted device)".

According to foreign media citing people familiar with the matter, one of the factors in the Neuralink study may be that Abo's brain entered the air after the implantation, a condition known as intracranial gas accumulation. This issue does not seem to pose a threat to Abo's security. Even so, researchers are considering the possibility of removing Abo's intracranial devices, people familiar with the matter said.

For Neuralink, which is seeking broader clinical trials, any failure could delay the FDA approval process.

Earlier in March, Neuralink announced the progress of Nolan's implant, saying that the tetraplegic man had been able to play games and online chess with his mind. Musk also said at the time that Nolan was recovering well and "seems to have fully recovered without the adverse reactions we know."

The brain-computer interface core is in the human or animal brain with the computer or itsFantasycryptoA new communication and control technology established between his electronic devices that does not rely on conventional brain information output pathways (peripheral nerve and muscle tissue). According to the path of communication technology, its technology is mainly classified into three categories: "non-invasive (out of the brain)", "invasive" and "semi-invasive".

Neuralink is invasive, that is, electrodes are directly implanted into the cerebral cortex by surgery to obtain high-quality neural signals. The N1 implant currently used by the company records neural activity through 1024 electrodes distributed over 64 threads, and the highly flexible ultra-fine electrode wire is the key to minimizing damage during and after implantation.

Neuralink said that efforts are being made to improve text input and cursor control of brain-computer devices, with the ultimate goal of extending to the physical world to achieve control of robotic arms, wheelchairs and other technologies, and to improve the independence of tetraplegic patients.

Musk has repeatedly claimed that implantable brain-computer interface devices can allow the paralyzed to walk again, let the blind gain eyesight, achieve "man-machine symbiosis" and so on.

Founded in 2016, Neuralink focuses on brain-computer interfaces to achieve "human-machine interaction" by developing devices that can be implanted into the brain. After the establishment of the company received several rounds of financing, according to foreign media reports, as early as June 2023, the valuation of Neuralink has exceeded 5 billion US dollars. In a round of 2 two years agoFantasycryptoOf the $0.05 million in private equity financing, Neuralink is valued at nearly $2 billion.
