Localized abnormalities in the cingulum bundle in patients with schizophrenia: A Diffusion Tensor tractography study
(Elsevier, 2014)
The cingulum bundle (CB) connects gray matter structures of the limbic system and as such has been implicated in the etiology of schizophrenia. There is growing evidence to suggest that the CB is actually comprised of a ...
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 ...
Human middle longitudinal fascicle: variations in patterns of anatomical connections
(Springer Science + Business Media, 2012)
Based on high-resolution diffusion tensor magnetic resonance imaging (DTI) tractographic
analyses in thirty-nine healthy adult subjects we derived patterns of connections and measures of volume and biophysical parameters, ...
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 ...
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 ...
On Describing Human White Matter Anatomy: The White Matter Query Language
(Springer Science + Business Media, 2013)
The main contribution of this work is the careful syntactical definition of major white matter tracts in the human brain based on a neuroanatomist’s expert knowledge. We present a technique to formally describe white matter ...
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 ...
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 ...
Corpus Callosum Abnormalities and Their Association with Psychotic Symptoms in Patients with Schizophrenia
(Elsevier BV, 2010)
Background—Whilst the neuroanatomical underpinnings of the functional brain disconnectivity observed in patients with schizophrenia remain elusive, white matter fiber bundles of the brain are a likely candidate given that ...
