Sentences with phrase «lower fractional anisotropy»

Blue indicates regions of the brain in which lower fractional anisotropy (a measure of microstructural integrity) correlated with more severe neurobehavioral symptoms.

Not exact matches

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).

Wolff and colleagues report that infants with ASD showed higher fractional anisotropy (FA) of most fiber tracts at 6 months followed by a slower change over time relative to infants without ASD such that by 24 months of age, the infants with ASD had lower FA values (Wolff et al., 2012).

The figure depicts increased fractional anisotropy in adolescents with Conduct Disorder with elevated callous - unemotional traits (CD / CU +) relative to those with Conduct Disorder with lower levels of callous unemotional traits (CD / CU --RRB-.

However, relatively few studies have investigated whether there are differences in brain structure between these subgroups.We acquired diffusion tensor imaging data and used tract - based spatial statistics (TBSS) to compare adolescents with CD and high levels of CU traits (CD / CU +; n = 18, CD and low levels of CU traits (CD / CU -; n = 17) and healthy controls (HC; n = 32) on measures of fractional anisotropy (FA), axial (AD), radial (RD) and mean (MD) diffusivity.
