AI tool can predict your IQ from brain scans



Scientists have developed a system of artificial intelligence that can show how clever someone is by looking at a scan of the individual's brain.

Researchers from the California Institute of Technology, the Cedars-Sinai Medical Center, and the University of Salerno, USA, show that their new computer tool can predict a person's intelligence through functional magnetic resonance imaging scans (fMRI) of their resting-state brain activity.

Functional MRI develops a map of brain activity by detecting changes in blood flow to specific brain regions

In other words, an individual's intelligence can be gained from patterns of activity in their brain when they are not doing or doing anything.

"We found out that we only leave people in the scanner and do it While we measure the activity pattern in their brain, we can use the data to predict their intelligence," said Ralph Adolphs of Caltech.

To Train Their Algorithm On the complex activity patterns in the human brain, researchers fed the brain scans and intelligence of nearly 900 individuals into their algorithm and set it in motion.

After processing the data, the algorithm was able to predict intelligence According to Julien Dubois, a postdoctoral fellow at Cedars-Sinai Medical Center, he had achieved statistically significant scores.

However, there is much room for improvement, he said.

The scans are rough and loud measurements of what actually happens in the brain, and many potentially useful information is still discarded.

The study was conducted as part of a continuing search for a diagnostic tool that can tell a person's brain a lot about their brains

Researchers said that they would like to see MRIs one day as well for diagnosis of conditions such as autism, schizophrenia, and anxiety, as they currently do to find tumors, aneurysms, or life

"Functional MRI has not yet delivered on its promise as a diagnostic tool, and we and many others are actively working to achieve this The availability of large data sets that can be obtained from scientists around the world makes this possible, "said Dubois.

Intelligence was selected as one of the first test fields for the technology, since research has shown that it is very stable over time. That said, a person's IQ score does not vary much over a period of weeks, months, or years years.

Researchers also conducted a parallel study using the same test population and approach that attempted to predict personality traits from fMRI

The personality test they use divides personality into five scales: openness to experience, conscientiousness, extraversion , Compatibility and Neuroticism

However, it has been found that it is much harder to predict personality using the method of predicting intelligence.
