A group of scientists has come up with a revolutionary device that allows paralyzed people to use their ideas to do things they never thought they could do with their lives.
The brain-computer interface known as BrainGate has already shown how it can help people with paralysis, but new research has shown that the device can be connected to a basic tablet that can send text messages. , view weather forecasts and even play the digital piano. A slice of aspirin in the brain of infected people will use the tablet.
The study, published last week in PLOS ONE, was conducted by scientists from Brown University, Providence Medical Center, Mbadachusetts General Hospital, and Stanford University. Three people with tetraplegia participated in the experiment, Cortex motor in their head.
The chip is equipped with 100 electrodes that send signals to the computer, which is able to detect certain types of activity, such as specific task ideas, and then translate them into commands executed on the device. Tablet PC.
Participants were able to use e-mail, e-chat, popular video sharing, weather verification, YouTube videos and online shopping. In one case, a volunteer was able to interpret Beethoven's famous "Ode to Joy" on a digital piano application.
With the help of this smart chip, participants can make up to 22 selections per single click per minute in different applications. For text-based apps, such as Google Hangouts and text messages, users can type up to 30 characters per minute.
"We used this knowledge to restore people's ability to master the same daily techniques as before their illness," said Dr. Jimmy Henderson, senior researcher and neurosurgeon at Stanford University. "It was great to see participants expressing themselves or simply singing what they want to hear."
Other studies by BrainGate have shown that this technique allows a woman with paralysis to drink coffee using only her ideas.
