5-min scan to know your child’s maturity
Scientists have developed a new brain scanning method that could reveal the maturity of a child’s brain, a technique they claim could also help track abnormal brain development and disorders like autism early.
The five-minute scanning technique involves mathematically sifting through magnetic resonance imaging (MRI) data to form a picture not just of the brain’s structure, but the way its various regions work together. “The beauty of this approach is that it lets you ask what’s different in the way that children with autism, for example, are off the normal development curve versus the way that children with attention-deficit disorder are off that curve,” said lead researcher Bradley Schlaggar at the Washington University School of Medicine in St. Louis.
According to the researchers, the tightest connections in young children’s brains are between areas that are physically near one another. As the brain ages, these connections shift and networks connecting distant regions become the strongest.
To measure these shifts over time, Schlagger and his colleagues used a method called resting state functional connectivity, LiveScience reported.
For their study, the researchers collected five-minute MRI scans from 238 healthy people ages seven to 30.
