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 ...
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 ...
Gray matter volume reduction in rostral middle frontal gyrus in patients with chronic schizophrenia
(Elsevier BV, 2010)
The dorsolateral prefrontal cortex (DLPFC) is a brain region that has figured prominently in studies of schizophrenia and working memory, yet the exact neuroanatomical localization of this brain region remains to be defined. ...
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 ...
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 ...
Excessive Extracellular Volume Reveals a Neurodegenerative Pattern in Schizophrenia Onset
(Society for Neuroscience, 2012)
Diffusion MRI has been successful in identifying the existence of white matter abnormalities in schizophrenia in vivo. However, the role of these abnormalities in the etiology of schizophrenia is not well understood. ...
A diffusion tensor imaging study of the anterior limb of the internal capsule in schizophrenia
(Elsevier BV, 2010)
Introduction—Frontal-subcortical cognitive and limbic feedback loops modulate higher cognitive functioning. The final step in these feedback loops is the thalamo-cortical projection through the anterior limb of the internal ...
A review of magnetic resonance imaging and diffusion tensor imaging findings in mild traumatic brain injury
(Springer Science + Business Media, 2012)
Mild traumatic brain injury (mTBI), also referred to as concussion, remains a controversial diagnosis because the brain often appears quite normal on conventional computed tomography (CT) and magnetic resonance imaging ...
Reduced fractional anisotropy and axial diffusivity in white matter in 22q11.2 deletion syndrome: A pilot study
(Elsevier BV, 2012)
Individuals with 22q11.2 deletion syndrome (22q11.2DS) evince a 30% incidence of schizophrenia. We compared the white matter (WM) of 22q11.2DS patients without schizophrenia to a group matched healthy controls using ...
