Researchers discovered that the “social” part of the brain in children with autism is underdeveloped, according to a recent study.
Researchers examined 17 children and young adults with an autism spectrum disorder (ASD), comparing them to 22 normally developing youths. They used imaging technology with magnetically-labelled blood water to trace blood flow. They specifically looked for something known as default mode network in the participants, who were all matched by age, sex and IQ scores.
From their research, the study authors also discovered reduced long-range connectivity between default mode network nodes located in the front and back of the brain in participants with ASD. Jann noted that a loss of connectivity suggests that information cannot properly flow between distant areas of the brain.
“The architecture of the brain follows a cost efficient wiring pattern that maximizes functionality with minimal energy consumption,” Jann added. “This is not what we found in our ASD participants.”
The study was published in the journal Brain and Behavior.
