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 ...
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. ...
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 ...
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 ...
Shape Differences in the Corpus Callosum in First-Episode Schizophrenia and First-Episode Psychotic Affective Disorder
(American Psychiatric Publishing, 2002)
Objective: The corpus callosum, the largest white matter tract in the brain, is a midline structure associated with the formation of the hippocampus, septum pellucidum, and cingulate cortex, which have been implicated in ...
Cingulate fasciculus integrity disruption in schizophrenia: a magnetic resonance diffusion tensor imaging study
(Elsevier BV, 2003)
Background: Evidence suggests that a disruption in limbic system network integrity and, in particular, the cingulate gyrus (CG), may play a role in the pathophysiology of schizophrenia; however, the cingulum bundle (CB), ...
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. ...
High-Resolution Line Scan Diffusion Tensor MR Imaging of White Matter Fiber Tract Anatomy
(2002)
Background and Purpose: MR diffusion tensor imaging permits detailed visualization of white matter fiber tracts. This technique, unlike T2-weighted imaging, also provides information about fiber direction. We present ...
Superior Temporal Gyrus Volume Abnormalities and Thought Disorder in Left-Handed Schizophrenic Men
(American Psychiatric Publishing, 1999)
Objective: Studies of schizophrenia have not clearly defined handedness as a differentiating variable. Moreover, the relationship between thought disorder and anatomical anomalies has not been studied extensively in ...
