Resting-State Brain Functional Connectivity Is Altered in Type 2 Diabetes
(American Diabetes Association, 2012)
Type 2 diabetes mellitus (T2DM) is a risk factor for Alzheimer disease (AD). Populations at risk for AD show altered brain activity in the default mode network (DMN) before cognitive dysfunction. We evaluated this brain ...
Estimation of Extracellular Volume from Regularized Multi-shell Diffusion MRI
(Springer Science + Business Media, 2012)
Diffusion MRI measures micron scale displacement of water molecules, providing unique insight into microstructural tissue architecture. However, current practical image resolution is in the millimeter scale, and thus ...
Age-related decline in white matter tract integrity and cognitive performance: A DTI tractography and structural equation modeling study
(Elsevier BV, 2012)
Age-related decline in microstructural integrity of certain white matter tracts may explain cognitive decline associated with normal aging. Whole brain tractography and a clustering segmentation in 48 healthy individuals ...
Alterations in brain structures underlying language function in young adults at high familial risk for schizophrenia
(Elsevier BV, 2012)
Introduction—Neuroanatomical and cognitive alterations typical of schizophrenia (SZ) patients are observed to a lesser extent in their adolescent and adult first-degree relatives, likely reflecting neurodevelopmental ...
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, ...
White Matter Integrity in the Brains of Professional Soccer Players Without a Symptomatic Concussion
(American Medical Association (AMA), 2012)
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 ...
Structural abnormalities in the cuneus associated with Herpes Simplex Virus (type 1) infection in people at ultra high risk of developing psychosis
(Elsevier BV, 2012)
It has been suggested that some cases of schizophrenia may be caused by an interaction between physiological risk factors and exposure to certain neurotropic infectious agents such as Herpes Simplex Virus type 1 (HSV1). ...
Longitudinal loss of gray matter volume in patients with first-episode schizophrenia: DARTEL automated analysis and ROI validation
(Elsevier BV, 2012)
Region of Interest (ROI) longitudinal studies have detected progressive gray matter (GM) volume reductions in patients with first-episode schizophrenia (FESZ). However, there are only a few longitudinal voxel-based morphometry ...
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 ...
