Left Auditory Cortex Gamma Synchronization and Auditory Hallucination Symptoms in Schizophrenia
(BioMed Central, 2009)
Background: Oscillatory electroencephalogram (EEG) abnormalities may reflect neural circuit dysfunction in neuropsychiatric disorders. Previously we have found positive correlations between the phase synchronization of ...
A new statistical method for testing hypotheses of neuropsychological/MRI relationships in schizophrenia: partial least squares analysis
(Elsevier BV, 2002)
We applied partial least squares (PLS) as a novel multivariate statistical technique to examine neuropsychological correlates of magnetic resonance imaging (MRI) measures of brain volumes in a well studied sample of 15 ...
Word priming in schizophrenia: Associational and semantic influences
(Elsevier BV, 2006)
We examined semantic vs. associational influences on word priming in schizophrenia. Tested on three occasions, subjects made speeded lexical decisions to three kinds of prime-word relationships: semantic-only (e.g., ...
Attentional networks and cingulum bundle in chronic schizophrenia?
(Elsevier BV, 2007)
Thirty patients with chronic schizophrenia and 30 age-matched controls performed the Attention Network Test (ANT). A subset of the patient group (n=18) also had available magnetic resonance diffusion tensor imaging (DTI) ...
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 ...
