Schizotypal personality disorder and MRI abnormalities of temporal lobe gray matter
(Elsevier BV, 1999)
Background: Structural MRI data indicate schizophrenics have reduced left-sided temporal lobe gray matter volumes, especially in the superior temporal gyrus (STG) and medial temporal lobe. Our data further suggest a ...
MRI Study of Caudate Nucleus Volume and Its Cognitive Correlates in Neuroleptic-Naive Patients With Schizotypal Personality Disorder
(American Psychiatric Publishing, 2002)
Objective: “Cognitive” circuits anatomically link the frontal lobe to subcortical structures; therefore, pathology in any of the core components of these circuits, such as in the caudate nucleus, may result in neurobehavioral ...
Uncinate Fasciculus Findings in Schizophrenia: A Magnetic Resonance Diffusion Tensor Imaging Study
(American Psychiatric Publishing, 2002)
Objective: Disruptions in connectivity between the frontal and temporal lobes may explain some of the symptoms observed in schizophrenia. Conventional magnetic resonance imaging (MRI) studies, however, have not shown ...
Voxel-Based Morphometric Analysis of Gray Matter in First Episode Schizophrenia
(Elsevier BV, 2002)
Voxel-based morphometry (VBM) may afford a more rapid and extensive survey of gray matter abnormalities in schizophrenia than manually drawn region of interest (ROI) analysis, the current gold standard in structural MRI. ...
Method for Combining Information from White Matter Fiber Tracking and Gray Matter Parcellation
(American Society of Neuroradiology, 2004)
We introduce a method for combining fiber tracking from diffusion-tensor (DT) imaging with cortical gray matter parcellation from structural high-spatial-resolution 3D spoiled gradient-recalled acquisition in the steady ...
Middle and Inferior Temporal Gyrus Gray Matter Volume Abnormalities in Chronic Schizophrenia: An MRI Study
(American Psychiatric Publishing, 2004)
Objective: The middle temporal gyrus and inferior temporal gyrus subserve language and semantic memory processing, visual perception, and multimodal sensory integration. Functional deficits in these cognitive processes ...
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 ...
Using the logarithm of odds to define a vector space on probabilistic atlases
(Elsevier BV, 2007)
The Logarithm of the Odds ratio (LogOdds) is frequently used in areas such as artificial neural networks, economics, and biology, as an alternative representation of probabilities. Here, we use LogOdds to place probabilistic ...
A 3D interactive multi-object segmentation tool using local robust statistics driven active contours
(Elsevier BV, 2012)
Extracting anatomical and functional significant structures renders one of the important tasks for both the theoretical study of the medical image analysis, and the clinical and practical community. In the past, much work ...
Diffusion Tensor Imaging and Its Application to Neuropsychiatric Disorders
(Ovid Technologies (Wolters Kluwer Health), 2002)
Magnetic resonance diffusion tensor imaging (DTI) is a new technique that can be used to visualize and measure the diffusion of water in brain tissue; it is particularly useful for evaluating white matter abnormalities. ...
