After the paralyzed person uses his brain to control the MIND to control the computer, the brain chip is considered to “change lives”



It may be the size of a paperclip, but this tiny brain implant reborn men with paralyzed upper limbs.

Synchron, a California-based neurovascular bioelectronics company, announced that its Stentrode Brain Computer Interface (BCI) allows patients to perform tasks on a computer with their own minds.

Using the implants, patients’ average click accuracy was 92% and 93%, respectively, and typing speeds were 14 and 20 characters per minute-no effort required.

The team is using blood vessels as natural pathways to the brain and attaching sensors that record activity to the blood vessels.

These signals are then sent via the telemetry unit to a small computer attached to the patient’s chest, which interprets the actions the patient wants to perform on the nearby PC, such as texting, emailing and online shopping.

When successful human trials took place, many companies were working tirelessly to develop the first brain chip-especially Elon Musk̵

7;s Neuralink, which only demonstrated its device in pigs.

Professor Peter Mitchell, Director of Neurological Intervention Services at the Royal Melbourne Hospital and principal investigator of the trial, said the findings are encouraging and prove that the device can be safely implanted and used in patients.

Professor Mitchell said: “This is the first time this kind of surgery has been performed, so we cannot guarantee that there will be no problems, but in both cases, the progress of the surgery is better than we hoped.”

The human test was conducted by two elderly people-Graham Felsted and Philip O’Keeffe.

The 60-year-old Felsted suffers from motor neuron disease (MND) and the 75-year-old O’Keeffe suffers from amyotrophic lateral sclerosis (ALS). As a result, neither of them can move their upper limbs.

The Stentrode device is small and flexible, and can safely bend blood vessels in the brain.

The research team pointed out that the procedure is similar to a pacemaker and does not require craniotomy.

After implanting the chip, the sensor is placed through the blood vessel and inserted into the internal telemetry unit, which is connected to a wireless transmitter strapped to the patient’s chest.

The sensor collects the activity of the brain and sends it to the transmitter, which interprets it as a computer task.

The system also includes an eye tracker for navigating the cursor on the computer screen.

Before the trial, both received machine learning assisted training to control multiple mouse clicks, including zooming and left-clicking.

Felsted said: “Using Stentrode has changed lives.”

With the help of this device, I was able to become productive again, including shopping, banking and delegating tasks among the Rotary club members I volunteered for. It is incredible to regain this independence.

He received the implant in August 2019 and is still using it today.

O’Keefe received his Stentrode device in April 2020, which allows him to control computer equipment to perform work-related tasks and other independent activities thereafter.

Philip O'Keefe (pictured), 75, received the Stentrode device in April 2020, which allows him to control computer equipment to perform work-related tasks and other independent activities.

Before using the chip, ALS damaged his fingers, elbows and shoulders, making it impossible to perform such tasks.

Synchron’s neurointerventionist and CEO Thomas Oxley said this is a breakthrough moment in the field of brain-computer interfaces.

Oxley said: “We are pleased to announce that we have provided a fully implantable, take-home wireless technology that does not require brain surgery. This technology can restore freedom for severely disabled people.”

“Our first product will focus on using brain pulses for smart device control without the need for hands.”

This alone is likely to meet the unmet market demand of 30 million patients in developed economies. “

Associate Professor Nicholas Opie of the University of Melbourne, co-head of the University’s Vascular Bionics Laboratory and the Chief Technology Officer of Synchron, said that this progress is exciting and the lives of the patients involved have been improved to a certain extent restore.

Associate Professor Opie said: “It is truly amazing to observe that participants using this system can communicate and control computers with their thoughts independently and at home.”

“We are very happy to work with such an outstanding participant, and my colleagues and I are honored to change their lives. I hope others will be inspired by their success.

The team noted that although these trials have shown success, it will take several years for the technology to be used by the public-but they are “working tirelessly to achieve this goal.”

In the past eight years, we have absorbed some of the world’s leading medical and engineering ideas, and created an implant that enables paralyzed people to control external devices with the power of thought. We are happy to report that we have achieved this goal. “

The research team pointed out that although these trials have shown success, the technology is still many years away before it becomes available to the public, but they are “working tirelessly to achieve this goal.”

After months of hype, Elon Musk showed off his Neuralink brain chip in August. The company “will show that neurons fire in real time.”

Although the CEO keeps his promise, the technology that many viewers want to see is shown in people, not pigs in live broadcasts.

As he claimed, the demonstration of the three little pigs showed an animal called Gertrude with an implanted brain. When she sniffed her nose with a pen, the audience saw her brain activity on the big screen.
