Mind reading breakthrough
Mind reading breakthrough Mind reading' breakthrough made, Scientists at a major university say they're one step closer to being able to read minds. The researchers claim to have invented a computer program that can "decode" some brain waves and transcribe the thoughts into words
In movies, machines and people can read your mind. Till we achieve that, a first step could be done, which would be quite a breakthrough: translate the thoughts of a paralyzed person into speech in a pioneering experiment. Jonathan Brumberg from Boston University revealed the results of his team at the meeting of the Society for Neuroscience in San Diego, California last week.
The researchers made their investigation
with Eric Ramsay, 27, a young man left paralytic by a car accident for eight years. He is well aware but he cannot express other way than through eye movements.
Now researchers, tracking cell signaling between the young man's brain cells, could translate his brain activity into sounds, according to The New Scientist.
In 2004, researchers implanted in the patient a wireless electrode, 6 mm below the surface of his brain, in the area known to trigger the impulses that go to the muscles of the tongue and mouth, resulting sound production and speech. After investigating the patterns of these nerve signals, triggered when Ramsey intended to speak, the researchers developed a software that could transform them into a computer "voice", which one day could generate blocks of words.
The investigations revealed a clear brain pattern forming when Ramsey attempted to pronounce the vowels "oh", "ee" and "oo". Various patterns were linked with many sounds, and the research team assesses that they can correctly say what Ramsey wanted to say in 80 % of the cases. In a few weeks, a computer could turn Ramsay's brain pattern signaling into sounds which will be audible in real time.
After vowels, the researchers will tackle consonants, the last step which will give Ramsey back the possibility to "speak". "Conversation is what we're hoping for, but we're pretty far from that," said Joe Wright of Neural Signals, a Duluth, Georgia, based company, which develop the technology employed by Ramsey.
The scientists chose Ramsey for their investigation because of his young age, which means he has a long further life expectancy and can withstand several investigations weekly.
You may idly wish you could hear what others are thinking yet write off telepathy as science fiction. But one day, the ability to read people’s minds may not be a talent reserved for psychics and the X-Men.
A group of neuroscientists at the University of California, Berkeley, reported they may have come up with a scientific way to read people’s minds.
Led by post-doctoral researcher Brian Pasley, the scientists have developed a method for deciphering the electrical signals in a person’s brain as they listen to words or conversation. Upon figuring out these signals, they were then able to use them to recreate the imagined speech of the same person.
The secret to their method lies in the temporal lobe of the brain, which is used in auditory perception. When a person hears a word or phrase being spoken, the activity that occurs in the temporal lobe also occurs when the person imagines that same word or phrase.
“This is a fundamental principle of the brain,” Robert Knight, a senior author for the study and a neuroscientist at UC Berkley, told FoxNews.com.
“The area that performs a cognitive or behavioral function is also activated when you imagine that function. For example, let’s say you raise your right arm. Then if you imagine raising your right arm, the same areas that were active when you move your arm are working when you imagine it.”
