>> MK, we can't use her name just her initials, has been trapped in her totally paralyzed body for two years. Complete locked-in syndrome has left her unable to even blink. Researchers in Geneva have found a way to decipher her thoughts. They spent 15 years monitoring blood oxygen levels in the brain, and can now read the physiological impact of locked-in patients thoughts.
>> This study shows that in fact you can communicate and these people are thinking and they're able to answer quite complex questions.>> The technique measures blood oxygenation and electrical activity in the brain while patients are asked questions.>> The machine records the blood flow during that thought and calculates how the blood flow changes hearing yes and hearing no.
And after a while as the computer develops an idea, a pattern of the blood flow during a yes and during a no.>>
> Questions with known answers are calculated correctly 70% of the time.>> So far, thanks to God, there was not a single patient who said he doesn't want to live.>> Counter to expectations, all four patients consistently answered yes when asked are you are happy? The team hopes one day to help those with paralysis resulting from amyotrophic lateral sclerosis or ALS, stroke, or spinal cord injury.
They say it could transform lives allowing completely locked-in patients to express feelings and opinion to loved ones and carers.
