"There are people afraid to go out in the fall on their own land," Sergeant Ray noted, explaining that there are brazen interlopers who try to foil property confiscation laws by surreptitiously using tracts of other people's land.
WM integrity was analyzed using tract-based spatial statistics.
Using tract-based spatial statistics, we investigated left-to-right differences in white matter microstructure across the whole brain.
Subsequently, we investigated group differences in every psychological score, correlations between fluency and delusions, and relationships between these scores and white matter integrity using tract-based spatial statistics (TBSS).
Individual subjects' FA measures were calculated from diffusion tracing imaging (DTI) data using tract-based spatial statistics—an approach specifically designed and validated for voxel-wise multi-subject FA analysis.
Diffusion tensor data (DTI) data were processed using TRActs Constrained by Underlying Anatomy (TRACULA) for automatic reconstruction of a set of major white-matter pathways from diffusion-weighted MRI.
Using tract-based spatial statistics, we correlated several diffusion parameters including the apparent diffusion coefficient, fractional anisotropy (FA), as well as axial and radial diffusivity with BMI and serum leptin levels.
While we observed significant reduction in the mean FA in the right fornix based on ROI analysis, there is only a trend of significance for FA decrease, RD and AD increase along the right fornix bundle using tract-based analysis.
Our finding of the mean FA reduction in the left fornix of patients with schizophrenia using tract-based analysis was consistent with findings of earlier studies where tract-based analysis were used [1], [25] but in contrast to studies using voxel-based analysis [42], [43].
Of course all anatomical studies, whether using tract-tracing with WGA-HRP or cytological in nature (e.g., Golgi-, Weigert- or Nissl-staining) particularly those done in earlier decades, will be limited by technical and methodological issues that make it difficult to draw firm conclusions about nuclear boundaries or patterns of connectivity.
