PARALYZED PEOPLE CAN TURN THOUGHT INTO TEXT WITH BRAIN IMPLANTS
Three paralyzed people used unmodified computer tablets to text, surf the internet and steam music, this all happened due to an electrode array system called BrainGate2. This is a major impact on the lives of those affected by neurological disease, injury or limb loss.
Working of the system:
The system uses an array of micro-electrodes implanted into the brain which decode, in real time, the neural signals associated with the intention to move a limb. In this trial, three people were involved, it had electrode grids implated over part of their motor cortex- brain’s area that helps to control movement, which picked up neural activity indicating they were thinking about moving a cursor on the screen, those patterns than sent to virtual mouse that wirelessly paired to the tablet.
In this all process only user’s intentions, the users were able to perform a range of common digital tasks including web browsing and sending email. One of them ordered groceries online and played a digital piano. “The tablet become second nature to me, very intuitive,” she told the researchers when asked about her experience, according to the study.
