Now, though, the man has had two microchips placed in his motor cortex which controls movement. While his family had feared that he’d soon be unable to communicate, those fears have now been negated.
The chips register activity in the brain, and when there is an increase in activity a rising sound plays on a device. When there is a decrease, the computer plays a descending tone.
Researchers Ujwal Chaudhary and Niels Birbaumer published their findings in Nature Communications. They call the method neurofeedback, with the patient able to see their activity recorded in real time and learn to control it.
Chaudhary said one of the first sentences the patient spelled out was: "Boys, it works so effortlessly."

While the system allowed him to ask for food and request to spend time with his family, there was one thing that he consistently asked for.
"Many times, I was with him until midnight, or past midnight. The last word was always 'beer',” Chaudhary added.
It’s the most recent study published in Nature Communications to make headlines over recent weeks, after three patients suffering from complete paralysis had their body movements rapidly restored thanks to a new implant.
The novel implant electrically stimulates the spinal cord and was found to restore body movements within a few hours of the onset of therapy in the patients, showed new research.
