Localized abnormalities in the cingulum bundle in patients with schizophrenia: A Diffusion Tensor tractography study
(Elsevier, 2014)
The cingulum bundle (CB) connects gray matter structures of the limbic system and as such has been implicated in the etiology of schizophrenia. There is growing evidence to suggest that the CB is actually comprised of a ...
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 ...
Word Recall in Schizophrenia: A Connectionist Model
(American Psychiatric Publishing, 1998)
Objective:The authors examined word recall of patients with schizophrenia by using an experimental paradigm generated from connectionist models of memory.Method:Schizophrenic patients and normal comparison subjects first ...
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., ...
Fiber geometry in the corpus callosum in schizophrenia: Evidence for transcallosal misconnection
(Elsevier BV, 2011)
Background—Structural abnormalities in the callosal fibers connecting the heteromodal association areas of the prefrontal and temporoparietal cortices bilaterally have been suggested to play a role in the etiology of ...
Attentional Control and Intelligence: MRI Orbital Frontal Gray Matter and Neuropsychological Correlates
(Hindawi Publishing Corporation, 2015)
Attentional control is a key function of working memory that is hypothesized to play an important role in psychometric intelligence. To test the neuropsychological underpinnings of this hypothesis, we examined full-scale ...
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) ...
Disruption of function–structure coupling in brain regions sub-serving self monitoring in schizophrenia
(Elsevier BV, 2013)
Deficits in self monitoring are a core feature of cognitive dysfunction in schizophrenia, and may be the basis for disturbances of self and lack of insight, ultimately impacting social functioning. However, the functional ...
Cerebral white matter abnormalities and their associations with negative but not positive symptoms of schizophrenia
(Elsevier BV, 2014)
Although diffusion tensor imaging (DTI) studies have reported fractional anisotropy (FA) abnormalities in multiple white matter (WM) regions in schizophrenia, relationship between abnormal FA and negative symptoms has not ...
