Scientists have come up with an artificial intelligence system that makes it possible to know how intelligent a person is by looking at a brain scanner of the individual
Researchers at the California Institute of Technology , Cedars-Sinai Medical Center and the University of Salerno. The United States shows that their new computer tool can predict a person's intelligence from functional magnetic resonance imaging (fMRI) of his resting brain activity
. Functional MRI develops a card of brain activity by detecting changes in blood flow to specific brain regions.
In other words, the intelligence of an individual can be drawn from the patterns of activity of his brain when he does not think or think of anything particular.
"We found out if we just had people in the scanner and nothing as we measure the pattern of activity in their brains, we can use the data to predict their intelligence," said Ralph Adolphs of Caltech .
To train their algorithm On the complex patterns of activity in the human brain, the researchers fed the scanning and intelligence algorithms of nearly 900 individuals in their algorithm and have it put to work.
After processing the data, the algorithm was able to predict According to Bernard Dubois, postdoctoral fellow at the Cedars-Sinai Medical Center, [traduction]
But there is a lot to be done to improve things. he said.
Scans are raw and noisy measurements of what really happens in the brain, and a lot of potentially useful information is still thrown away.
The study was conducted as part of an ongoing quest to build a diagnostic tool that could say a lot about a person 's mind.
The researchers said that they would like to see MRI one day work as well to diagnose conditions like autism, schizophrenia, and anxiety as they currently do to find tumors, aneurysms, or live
"The functional MRI has not yet kept its promise as a diagnostic tool.We and many others are actively working to change The availability of large data sets that can be exploited by scientists around the world makes this possible, "said Dubois
.The intelligence was chosen as one of the first benches to Test for technology, that is to say that the IQ of a person does not vary much over a period of several weeks, months or years.
The researchers also conducted a study parallel using the same population and the same test approach. Onnality that they used divides the personality into five scales: openness to experience, consciousness, extroversion, amenity and neuroticism
However, he It's proven much harder to predict personality using the following method: team used to predict intelligence.
