The patient spelled out his enthusiastic relief with the technology. 🧠
is a system that acquires brain signals, analyses them, and then converts them into commands that can be relayed over an output device. A common example of such as system is Neuralink which has enabled experimental monkeys to play computer games without using a joystick.
While watching a monkey play pong using his mind might be exciting, the main aim of the technology is to improve the quality of life of individuals who have lost critical functions of their body due to disease or accidents. Sign up here for freeA 37-year-old man, called patient K1, is affected with Lou Gehrig's disease, also known as amyotrophic lateral sclerosis . It's a condition where individuals gradually lose the ability to control the muscles in their bodies.
While these devices have evolved over the years, they still need the individual to retain some amount of muscular control either in the eyes or facial muscles to continue using them. In the case of ALS, the condition of patients continues to deteriorate as they lose control of muscles all over the body, called the"completely locked-in" state. The team of researchers at Tubingen led by Dr.
K1, who was diagnosed with his condition in 2015, lost the ability to walk later that year. He began using an eye-tracking AAC device in 2016 but his ability to fix his gaze the following year. The family used their own method to communicate yes and no responses depending on eye movements, but that was soon lost as well. In 2019, the researchers implanted two microelectrodes into the patient's brain and began using auditory feedback to train the device.
The system is far from perfect and runs the risk of getting stuck in a loop and requires that it be used under supervision. The researchers are also working on an improved version of the system that does not need an external computer to function. The system is currently under prevalidation. .Patients with amyotrophic lateral sclerosis can lose all muscle-based routes of communication as motor neuron degeneration progresses, and ultimately, they may be left without any means of communication.
