When observed with the naked eye, the human brain is divided into gray matter and white matter according to its color. The gray matter is mainly concentrated in the shell of the brain, and the white matter is located between the gray matter and the gray matter. In the general brain, 40% gray matter and 60% white matter. The gray matter plays a role in receiving information coming into the brain, and the white matter serves as a pathway for information transmission between the gray matter and the gray matter.
Adolescents and young adults with autism show significant differences in brain white matter when compared to their non-autistic peers, a new study finds. Based on the research results of Yale University Medical School to be presented at the annual general meeting of the North American Radiological Society, the US health and medicine news webzine Health Day reported on the 23rd.
The Yale University researchers compared the brains of 264 patients with autism between the ages of 6 months and 50 years and a control group of 319 without autism by using diffusion tensor imaging (DTI). DTI is one of the magnetic resonance imaging (MRI) techniques that measure the connectivity of the brain by paying attention to the fact that the movement speed is different depending on whether the brain tissue is gray matter or white matter.
The researchers found differences between adolescents with autism and young adults and similar-age controls. It was investigated that the white matter of the medial and mid-cavity passages of the cranial girdles, which are bundles of nerve fibers located between the left and right hemispheres, were different. In particular, the difference was more pronounced for young adults than for adolescents.
“If you think of gray matter as a computer, white matter is like a cable,” said Clara Weber, one of the researchers. said. “One in 68 children in the United States has autism, but it is difficult to diagnose early and verify the effectiveness of treatment,” he said. He added that he plans to proceed.
