Neuron interfaces are still trying to happen and I am skeptical about 90% of the undertaking; As for Big Tech, thanks to my gray there is a “closed” sign, thanks. Despite this, the remaining 10% of the brain-Computer projects presents real medical progress that is worth getting excited about.
A team of scientists from the Feinstein Institutes for Medical Research in Manhasset in New York has created a cerebral interface feel They also also (via IEEE Spectrum). The team is managed by Chad Bouton, vice president for advanced engineering at the Institute, and achieved the above -mentioned “double neural beltway” system, which they worked on at least 2015. Cutting long -term financing of medical research is a compact -sighted movement at best.
In any case, let’s keep it positive. This original experiment from 2015 created a single “neural bypass” – basically a number of electrodes implanted directly to the patient’s motor cortex. This brain chip would listen to neural activity, and the AI model would match the upcoming waves of the patient’s intended movements. The latest experiment of the “Double Neuron Ripper” of the team opens another communication channel, enabling the movement of sensual data to the patient’s brain. However, instead of implantation, only two brain chips, as suggested by the term “double neural beltway”, the patient at the Feinstein team research center was equipped fiveincluding a total of 224 electrodes in its gray matter.
Keith Thomas is the patient in question, first paralyzed from the chest after a diving accident. Before participating in the experiment, Feinstein Thomas was able to lift his hand from the arm of a wheelchair by around inch.
To return movement and feeling to paralyzed limbs, the band implanted two electrode boards to Thomas’s motor cortex, along with three similar systems in its somatosensory bark (a piece of brain responsible for touch). The AI model interpreted Thomas’s brain signals, and then stimulated further electrode systems implanted in his neck and shoulder. They were used to modulate the core and forearm of the patient, properly, enabling movement.
During the experiment, Thomas was able to rebuild strength in his shoulder. He is now able to reach and touch his face or drink from a cup without support. Adding stimulation of somatosensory bark also means that Thomas can feel what it affects, allowing him to better modulate the strength of adhesion and, as the band claims, lift the empty egg shell without cracking.
Even more invigorating is that Thomas can now feel a certain impression in his shoulder, even if it is not connected to the “double neural beltway” system. Scientists are not entirely sure why this is so, but it is possible that neuroplasticity allowed Thomas to “bear” the brain “how to interpret sensory information.
The leader of the research team, Chad Bouton, explained: “It is known that from animal experiments electrical stimulation can promote neurons growth, but here it is not clear whether it is about strengthening saved connections at the spinal cord damage. At the moment we know that the results are significant and lead to functional and significant results.”
Scientists from the whole field successfully return movement to paralyzed limbs through cerebrospinal interfaces For years. In fact, one early experiment of the neural beltway even returned the impressive range of motion to one teenage man He was able to play Guitar Hero again. However, these experiments were largely a one -way, returning street, but NO Sensation – now.
This is also not the first time AI was implemented as a really supporting technology; According to my count, the last really helpful thing that the finish line as a company was conducting research that one day could allow people with difficulties in speech through the AI neural interface. A few more scientific jumps and I can toasty up to the idea of a brain chip.
