Go, Ilon Musk: Scientists one step towards creating a brain-computer interface

The transparent graphene sensor was able to read the data that transmit neurons, and artificial intelligence was able to understand and decipher them. Researchers at the University of California at San Diego (USA) have created a thin transparent neural implant that can monitor the activity not only on the brain surface but also at a deeper level. The device can be the first step towards creating the exact interface "Brain-Computer", reports New Atlas.

Implants that read activity deep inside the human body consist of probes that cause problems such as inflammation and scarring. The downside is that the signals they give can deteriorate over time. Implants located on the surface of the brain have no such problems, but they can give scientists nothing but signals spreading the brain surface. Scientists at the University of California at San Diego seem to be able to solve these problems.

They created a supra -thin polymer film consisting of two layers of transparent graphene wires clamped around a layer of nitric acid. Putting a transparent film on the brain of mice, the researchers were able to read the rodent brain surface signals. Due to the fact that the device is transparent, the developers were able to simultaneously pass the lasers through it and use a two -photon microscope to produce the image of calcium thorns in neurons, which were located at a depth of 0.

25 mm below the surface. And calcium is known to be a key component of data exchange between neurons. The researchers were then able to teach the SI model to establish a connection between the superficial and the superficial activity, in fact, teaching it to "understand" what happens in the depths of the brain. "With this technology, we expand the spatial coverage of neural records," said the participant of the study of Duhu Kuzum.

- "Despite the fact that our implant is on the surface of the brain, its design makes it possible to go beyond physical perception, as it can determine neural activity from deeper layers of the brain. " Researchers also say that to observe the activity of calcium inside the brain, they need to fix the head under the microscope during procedures that can last up to 2 hours. However, the new graphene implant does not have such a restriction.

"Our technology makes it possible to conduct longer experiments in which the subject can move freely and perform complex behavioral tasks," said the co -author of the study Mehrdad Ramzani. "This can provide a more complete understanding of neural activity in the dynamic scenarios of the real world. " Scientists plan to check the work of their transparent graphene sensor on other animals, and then perhaps on humans.
