CortiCom is a device that reads thoughts and translates them into commands for smart devices.
Scientists from Johns Hopkins Medical University and the Johns Hopkins University Applied Physics Laboratory have made a significant breakthrough in the field of brain-computer interfaces (BCI). Their device, known as" Cortical Communication " or CortiCom, was successfully tested on patients with amyotrophic lateral sclerosis (ALS). CortiCom allowed patients to regain some of the functions they had lost due to the disease.
The essence of the new technology is to implant a device on the surface of the brain that controls speech and movement of the upper extremities. The researchers found that CortiCom allows patients to freely control devices with six basic commands, such as "up", "down", "left", "right", "enter" and "back". These commands allow patients to interact with smart devices, such as changing the lighting in the room or controlling applications on the TV.
"At this point, this is a very important development in the field of brain - computer interfaces," says Nathan Crone, professor of neurology at Johns Hopkins Medical University and principal investigator of the clinical trial. "We focused on enabling patients to directly control smart devices, not just restore communication. CortiCom successfully recognizes simple commands, enabling patients to interact with the world without the need to adjust speech recognition"".
For best results, the researchers used information from the motor and sensory areas of the brain responsible for lip, tongue, and jaw movements. During the three months of testing, these brain regions remained stable, which underlines the reliability of the device.
However, one of the most encouraging things is that CortiCom showed stable performance for three months without the need to recalibrate or re-train the algorithm. This means that the device maintains its accuracy and reliability for a long time.
"For those who have lost the ability to communicate due to various neurological conditions, there is great hope to maintain or restore the ability to communicate with family and friends. But there is still a lot of work to be done to make the technology available to all patients who might benefit from it," Crone concluded.
Researchers are now actively seeking participants for further clinical trials aimed at improving CortiCom.
