Sentences with phrase «compared gray matter volumes»

Not exact matches

Using brain scans to compare the gray matter of children with RAD to typically developing children, the researchers found significantly reduced volume of gray matter in the area of the brain known as the left primary visual cortex.

Through analysis of high - resolution anatomical magnetic resonance imaging of brain volumes, taken three times over the two - year study period, the researchers were able to determine that individuals with MCI or Alzheimer's showed greater losses in gray matter volume in both the basal forebrain and temporal lobe, compared with cognitively normal controls.

Comparing MRI brain images of eight Dobermans with CCD to the control group, Ogata found that the CCD group had higher total brain and gray matter volumes, lower gray matter densities in the dorsal anterior cingulate cortex and right anterior insula, and higher fractional anisotropy in the splenium of the corpus callosum (the degree of which correlated with the severity of the behavioral traits).

In addition, they determined that volumes of human prefrontal gray and white matter match the expected volumes for the number of neurons and other cells in the white matter when compared to other primates.

One report found significantly greater decreases in gray matter volume in children with autism scanned at two time points (age ~ 11 and at 30 - month follow - up) compared with TD children (Hardan et al., 2009).

Because human gray matter follows a nonlinear developmental trajectory, we established a reference for typical development in focal brain areas and constructed an index that measured whether regional gray matter volume was larger or smaller than expected, comparing children with others of the same sex and age.
