Image: These brain images, captured with DTI MRI, show water diffusion within the white matter of children with sensory-processing disorders (SPDs). Row FA: The blue areas show white matter where water diffusion was less directional than in typical children, indicating impaired white matter microstructure. Row MD: The red areas show white matter where the overall rate of water diffusion was higher than in typical children, also indicating abnormal white matter. Row RD: The red areas show white matter where SPD children have higher rates of water diffusion perpendicular to the axonal fibers, indicating a loss of integrity of the fiber bundles comprising the white matter tracts (Photo courtesy of the University of California, San Francisco - UCSF).
