A ‘mind-reading’ device that can decipher words from brainwaves without them being spoken has been developed by Japanese scientists, raising the prospect of ‘telepathic’ communication.
Researchers have found the electrical activity in the brain is the same when words are spoken and when they are left unsaid.
By looking for the distinct wave forms produced before speaking, the team was able to identify words such as ‘goo’, ‘scissors’ and ‘par’ when spoken in Japanese.
The scientists behind the technology said they can identify brain waves associated with syllables or letters of the Japanese alphabet, meaning it may be possible to decode entire words and sentences without the need for any of them being physically spoken.
