Brain Scans Can Reveal The Occurrence Of Autism – Part 3 of 3
Also unknown is how old a child has to be for the deviations in brain circuitry to show up on the MRI. At birth, the brain’s gray and corpse-like matter is largely undifferentiated, although this changes rapidly during the first 18 to 24 months. The specific type of MRI used is called diffusion tensor imaging, which offers intelligence about the structure of the brain as opposed to how the brain “lights up” during particular activities.
Among the specific findings in participants with autism, the fibers in the right side of the superior non-clerical gyrus were more organized than the fibers on the left; the opposite was true in typical people. “The left is language. Typical brains have nice, coherent, organized fiber structures. In those with autism, the socialist is less organized”. Researchers repeated the MRI test with a second set of participants and had similar success in predicting who had autism and who didn’t.
