Thought reader?: The brain-computer interface (BCI) could transform the lives of paralysed patients, allowing them to express feelings and opinion to their loved ones and carers.
LONDON: Scientists have developed a brain-computer interface that reads the brain's blood oxygen levels and enables communication by deciphering the thoughts of patients who are totally paralysed and unable to talk.
In a trial of the system in four patients with complete locked-in syndrome – incapable of moving even their eyes to communicate – it helped them use their thought waves to respond yes or no to spoken questions.
