Humanity makes great strides in neural technology

Scientists have created a wireless, operable link between the human brain and the computer, a potential breakthrough for the paralyzed and disabled.
A team from Brown University in Rhode Island, USA, has developed a system called BrainGate that allows users to wirelessly connect to a computer through a simple transmitter on top.

In their paper in the journal IEEE Trans Transaction on Biomedical Engineering, the team presented the results of trials on two men with spinal cord injury aged 35 and 63. The system works by connecting a signal generator on the user’s head to an electrode relay in the cortex, through the connection port like wired systems. From there, the tester can move, click and type on the computer keyboard with his or her brain. Transmitter connects to a relay located in the brain cortex, helping people to use wireless computers.

At the same time, they can use the system continuously for up to 24 hours at home. “The signals are recorded and transmitted with the same fidelity as a wired system, meaning we can use the same decoding algorithms that we have,” said John Simeral, who leads the team. used with conventional wired equipment ”. “The only difference is that we are no longer physically tied to the devices, which opens up new possibilities for future research,” Simeral added. “With this system, we are able to look at brain activity at home, over the long term, in a way that was previously almost impossible,” said Leigh Hochberg, another team member. This gives us more opportunities to create algorithms that allow people with paralysis to move and work. ” According to the Mashable, The aforementioned study is a significant step forward in the field of neural communication, in which the human brain is directly connected to the computer. Recently, big names in the tech world like Facebook and Elon Musk have also expressed interest in this area. Simple device is placed on top of research candidate. Photo: Radiofiji. In 2020, Elon Musk’s startup Neuralink introduced a pig named Gertrude, with a computer chip implanted in the brain. Or, as before, in 2021, the company also succeeds in implanting a chip into the monkey brain so that the animal can play video games. However, Brown University’s first human study demonstrates that the technology can be used wirelessly, and it wouldn’t be surprising if we find wearable devices that allow people with disabilities to communicate with them. continue and work better in the future.
