Paralysed man's mind is 'read'
Electrodes were planted in the part of the brain which controls speech
Scientists say they may be on the brink of translating into words the thoughts of a man who can no longer speak, after a pioneering experiment.
Electrodes have been implanted in the brain of Eric Ramsay, who has been "locked in" - conscious but paralysed - since a car crash eight years ago.
These have been recording pulses in areas of the brain involved in speech.
Now, New Scientist magazine reports, they are to use the signals he generates to drive speech software.
Although the data is still being analysed, researchers at Boston University believe they can correctly identify the sound Mr Ramsay's brain is imagining some 80% of the time.
In the next few weeks, a computer will start the task of translating his thoughts into sounds.
"We hope it will be a breakthrough," says Joe Wright of Neural Signals, which has helped develop the technology.
"Conversation is what we're hoping for, but we're pretty far from that."
