fMRI helps show physiologic differences in autistic children

By combining functional MRI (fMRI) and passive speech stimulation, researchers at Columbia University Medical Center in New York have discovered physiologic differences between autistic and healthy children, according to a study in the August issue of Radiology.

Functional MR images of the superior temporal gyrus and primary auditory cortex of the brain, which are associated with sentence comprehension, demonstrate the “potential utility of fMRI as an objective indicator of language impairment in autism,” wrote a research team led by Grace Lai, PhD, of Columbia’s Functional MRI Research Center.
