  1. The structural neurobiology of social anxiety disorder : a clinical neuroimaging study

    Hattingh, Coenraad JacobusDepartment of Psychiatry and Mental Health2015

    … matter structure were performed using FSL's tract - based spatial statistics comparing fractional anisotropy (FA), mean diffusivity (MD) in individuals with SAD. Manual tracing demonstrated that compared to controls, SAD patients showed an enlarged right globus pallidus. Cortical thickness …

  2. Relationship between white matter changes and aggression in methamphetamine dependence

    Lederer, Katharina JohannaDepartment of Psychiatry and Mental Health2015

    … voxel wise comparison across subjects using tract based spatial statistics (TBSS) in FSL was used. Fractional anisotropy (FA), mean diffusivity (MD), parallel diffusivity (λ║) and perpendicular diffusivity (λ┴) were compared between the two groups. Second, a region of interest (ROI) …

  3. Brain Connectivity in Autism Spectrum Disorder

    Catani, MarcoKing's College London2012

    … consisted in the creation of a diffusion tensor tractography atlas of the normal human brain derived from 40 healthy adults. The atlas was then used to localise the findings from a metaanalysis of published voxel-based morphometry studies investigating white matter abnormalities in ASD. This …

  7. Using open-source data repository initiatives to investigate impaired white matter connectivity in autism

    Otto, Stephanie Rene2022

    … a total of 336 subjects (187 ASD, 149 NT) using Tract Based Spatial Statistics (TBSS). Due to the nested nature of the data, robust linear mixed-effects modeling was used to examine if group differences in diffusion measures were indicated while controlling for several covariates. Compared to NT …
