According to the latest news from the website of Popular Science in the United States, the artificial intelligence (AI) brain implantation technology developed by the Feinstein Institute of Biomedical Sciences at the Northwell Health Center in the United States can help paralyzed patients recover their senses and movements. Keith Thomas suffered a car accident in 2020, which resulted in injuries to his C4 and C5 vertebrae and a complete loss of sensation and motor ability below the chest. However, Thomas is now able to move his arms freely and feel his sister holding his hand. The research team spent several months mapping his brain using magnetic resonance imaging to determine the exact locations in his brain responsible for arm movement and hand touch. Four months ago, surgeons performed a 15 hour surgery to implant a microchip into his brain. During the surgery, certain parts of Thomas were even felt, and when the doctor detected certain parts of the organ, he could tell the doctor what sensation was produced. The microchip is located inside the patient's body, but an external port is installed on top of his head and connected to the computer. The newly developed algorithm can explain his idea and send signals to electrode patches in the spine and hands, which can then be converted into action. Researchers refer to this method as mind driven therapy, and through this technology, Thomas achieved the ability to move his arms freely. Researchers say that although connecting to a computer is necessary to achieve these actions, even if the system shuts down, Thomas shows signs of recovery. Since the start of the study, his arm strength has more than doubled, and his forearms and wrists can now feel some new stimuli. If everything goes smoothly, mind driven therapy may help him recover more tactile and motor abilities. Chad Burton, the technology developer and chief researcher in clinical trials, stated that this is the first time that the paralyzed human brain, body, and spinal cord have been electronically connected together to restore sustained movement and sensation. When a research participant wants to move their arm or hand, "boosting" their spinal cord and stimulating their brain and muscles can help rebuild connections, provide sensory feedback, and promote recovery.
