Mark Jackson is Playing a computer game with his mind. When it rests on the bed, three blue wheels appear on the laptop screen. One becomes red: goal. Jackson controls the white circle, which he must go to his destination without falling on blue obstacles. The game is a bit like PAC-Man. With the exception of the Jackson joystick, he uses his thoughts to control his little white circle. Moving left, he once thinks about tightening the right fist. To move to the right, thinking about doing it twice in a row, like a double click.
Jackson, who is 65 years senior and paralyzed, is good in this game. It consists of a red wheel. Becomes blue and makes it satisfying Ding! He hit the target. In the next round the circles change their position. He goes to the next round and the next and succeed 14 by 15 times. Earlier he received 100 percent in this game. On the other hand, he had practice.
A few years ago, surgeons in Pittsburgh implanted Jackson with an experimental cerebrospinal interface or BCI. Startup made by the Fresh York Synchron Synchron, decodries Jackson’s brain signals to follow the instructions on the laptop and other devices. It is one of 10 people – six in the USA and four in Australia – which received a synchronous implant as part of an early feasibility study. In addition to BCI games, he allows him to send text messages, write e -mile and shop online.
Jackson’s medical saga began about five years ago, when he lived in Georgia and worked for a wholesale flower company – his dream work. He thought he had pinched the nerve in his neck. But in January 2021, doctors from Emory University told him that the diagnosis was much more sedate: atrophic lateral sclerosis. Neurodegenerative disease, ALS, causes that nerve cells in the brain and spinal cord break down over time, which causes a gradual loss of muscle control. Jackson’s doctor asked if he was interested in joining the clinical examination of the ALS drug testing. Jackson said it was obvious.

But by December 2022 he lost his ability to write or raise buckets of flowers at work and had to stop working. He moved in with his brother on the outskirts of Pittsburgh. “Loss of mobility, the loss of independence that concerns this disease,” says Jackson, “it’s a lot to accept, it’s a lot to process.” He tried to remain positive, even when his illness was developing. When the drug examination ended in the summer of 2023, he willingly joined another examination that had a chance to lend a hand ALS.
The process of BCI Synchron has just begun at the University of Pittsburgh. While the implant would not snail-paced down the progress of Als Jackson, he could restore him some autonomy, which he lost his illness. “I was excited immediately,” says Jackson.
He began the verification process in July 2023, and six weeks later Jackson was in the operating room. In about a three -hour procedure, the surgeons put on a stentrode for the first time, a tube with a wire force of the size of a match, into his cervical vein at the base of the neck. Using the catheter, they carefully moved the device through the vessel, next to the ear and the side of the head, to resist the motor cortex, part of the brain, which controls voluntary movement. Then they inserted a tiny rectangular device under Jackson’s collarbone, which processes the brain signals and radiates them with infrared outside the body. These signals are collected by a shoulder -shaped receiver, which is located on Jackson’s chest, and then sent by wire to the unit, which translates them into commands. When the system is connected, a pair of green lights shines through his shirt.
