Semantic disturbance in schizophrenia and its relationship to the cognitive neuroscience of attention
(Elsevier BV, 2001)
We view schizophrenia as producing a failure of attentional modulation that leads to a breakdown in the selective enhancement or inhibition of semantic/lexical representations whose biological substrata are widely distributed ...
Abnormal Angular Gyrus Asymmetry in Schizophrenia
(American Psychiatric Publishing, 2000)
Objective: Few studies have evaluated the parietal lobe in schizophrenia despite the fact that it has an important role in attention, memory, and language—all functions that have been reported to be abnormal in schizophrenia. ...
Early nicotine withdrawal and transdermal nicotine effects on neurocognitive performance in schizophrenia
(Elsevier BV, 2008)
As cigarette smoking prevalence rates approach 90% in schizophrenia, an important emerging question is the role of nicotine in the disease-related disturbance in cognition. We therefore tested a total of 38 male cigarette ...
Orbitofrontal volume deficit in schizophrenia and thought disorder
(Oxford University Press (OUP), 2008)
Orbitofrontal Cortex (OFC) structural abnormality in schizophrenia has not been well characterized, probably due to marked anatomical variability and lack of consistent definitions. We previously reported OFC sulcogyral ...
Abnormal Neural Synchrony in Schizophrenia
(2003)
Schizophrenia has been conceptualized as a failure of cognitive integration, and abnormalities in neural circuitry (particularly inhibitory interneurons) have been proposed as a basis for this disorder. We used measures ...
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 ...
Dissociable contributions of MRI volume reductions of superior temporal and fusiform gyri to symptoms and neuropsychology in schizophrenia
(Elsevier BV, 2007)
We sought to identify the functional correlates of reduced magnetic resonance imaging (MRI) volumes of the superior temporal gyrus (STG) and the fusiform gyrus (FG) in patients with chronic schizophrenia. MRI volumes, ...
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. ...
Neuropsychological disturbance in schizophrenia: A diffusion tensor imaging study.
(American Psychological Association (APA), 2008)
Patients with schizophrenia and healthy control subjects underwent both neuropsychological evaluation and magnetic resonance diffusion tensor imaging, during which the cingulum bundle (CB) and the uncinate fasciculus (UF) ...
Comparing prefrontal gray and white matter contributions to intelligence and decision making in schizophrenia and healthy controls.
(American Psychological Association (APA), 2010)
We examined the relationship between neuropsychological performance and magnetic resonance imaging (MRI) of the orbital frontal cortex (OFC) and diffusion tensor imaging (DTI) of the cingulum bundle (CB) within groups of ...
