Brain Reading Scanner Reads all that’s on Your Mind
In the very near future there may be someone who may be reading your thoughts, literally!
A team of neuroscientists from University of California, Berkeley may soon be able to use brain-scanning instruments to read someone’s mind.
The research is being led by Dr. Jack Gallant, a neuroscientist at the renowned institute. According to Gallant, his team has discovered as to how exactly the functional magnetic resonance imaging (fMRI) can be employed to determine what someone is looking at on the basis of brain activity.
The method was tested on two members of the team who volunteered to view a series of images.
In the first phase, the volunteers looked at 1,750 photographs while being scanned by fMRI.
In the second step, the volunteers watched a new set of 120 images; the fMRI machine program accurately identified what they were looking at up to 92 percent of the time.
“When the deck of cards, or photographs, has about 120 images, we can do better than 90 percent correct,” noted Gallant.
As per a report, published online in the journal Nature, it is the pioneering move to being able to see the contents of someone’s visual experiences.
The next step is apparently to construe what someone is seeing without having the subject select from known images.
Acute conditions such as damage from strokes, the effect of drug treatments, or the detection of early symptoms of neurological diseases like Alzheimer’s and Parkinson’s can be done through a device that reads out the brain’s activity.
