Genetic contributions to changes of fiber tracts of ventral visual stream in 22q11.2 deletion syndrome
(Springer Science + Business Media, 2013)
Patients with 22q11.2 deletion syndrome (22q11.2DS) represent a population at high risk for
developing schizophrenia, as well as learning disabilities. Deficits in visuo-spatial memory are
thought to underlie some of the ...
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 ...
Cerebral white matter abnormalities and their associations with negative but not positive symptoms of schizophrenia
(Elsevier BV, 2014)
Although diffusion tensor imaging (DTI) studies have reported fractional anisotropy (FA) abnormalities in multiple white matter (WM) regions in schizophrenia, relationship between abnormal FA and negative symptoms has not ...
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 ...
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 ...
Gray matter alterations in early aging: A diffusion magnetic resonance imaging study
(Wiley-Blackwell, 2013)
Many studies have observed altered neurofunctional and structural organization in the aging brain. These observations from functional neuroimaging studies show a shift in brain activity from the posterior to the anterior ...
CNTNAP2 polymorphisms and structural brain connectivity: A diffusion-tensor imaging study
(Elsevier BV, 2013)
CNTNAP2 is a gene on chromosome 7 that has shown associations with autism andschizophrenia, and there is evidence that it plays an important role for neuronal synchronization and brain connectivity. In this study, we ...
Anterior limb of the internal capsule in schizophrenia: a diffusion tensor tractography study
(Springer Science + Business Media, 2012)
Thalamo-cortical feedback loops play a key role in the processing and coordination of processing and integration of perceptual inputs and outputs, and disruption in this connection has long been hypothesized to contribute ...
