Fiber geometry in the corpus callosum in schizophrenia: Evidence for transcallosal misconnection
(Elsevier BV, 2011)
Background—Structural abnormalities in the callosal fibers connecting the heteromodal association areas of the prefrontal and temporoparietal cortices bilaterally have been suggested to play a role in the etiology of ...
Statistical analysis of fiber bundles using multi-tensor tractography: application to first-episode schizophrenia
(Elsevier BV, 2011)
This work proposes a new method to detect abnormalities in fiber bundles of first-episode (FE) schizophrenia patients. Existing methods have either examined a particular region of interest (ROI) or used voxel based morphometry ...
Voxel-based morphometry (VBM) studies in schizophrenia—can white matter changes be reliably detected with VBM?
(Elsevier BV, 2011)
Voxel-Based Morphometry (VBM) is a hypothesis-free, whole-brain, voxel-by-voxel analytic method that attempts to compare imaging data between populations. Schizophrenia studies have utilized this method to localize differences ...
Stochastic tractography study of Inferior Frontal Gyrus anatomical connectivity in schizophrenia
(Elsevier BV, 2011)
Background—Abnormalities within language-related anatomical structures have been associated with clinical symptoms and with language and memory deficits in schizophrenia. Recent studies suggest disruptions in functional ...
Sparse Multi-Shell Diffusion Imaging
(Springer Science + Business Media, 2011)
Diffusion magnetic resonance imaging (dMRI) is an important tool that allows non-invasive investigation of neural architecture of the brain. The data obtained from these in-vivo scans provides important information about ...
White Matter Bundle Registration and Population Analysis Based on Gaussian Processes
(Springer Science + Business Media, 2011)
This paper proposes a method for the registration of white matter tract bundles traced from diffusion images and its extension to atlas generation. Our framework is based on a Gaussian process representation of tract density ...
