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 ...
Chronic Ketamine Reduces the Peak Frequency of Gamma Oscillations in Mouse Prefrontal Cortex Ex vivo
(Frontiers Media S.A., 2013)
Abnormalities in EEG gamma band oscillations (GBO, 30–80 Hz) serve as a prominent biomarker of schizophrenia (Sz), associated with positive, negative, and cognitive symptoms. Chronic, subanesthetic administration of ...
From Semantics to Feelings: How Do Individuals with Schizophrenia Rate the Emotional Valence of Words?
(Hindawi Publishing Corporation, 2012)
Schizophrenia is characterized by both emotional and language abnormalities. However, in spite of reports of preserved evaluation of valence of affective stimuli, such as pictures, it is less clear how individuals with ...
Emotional Cues during Simultaneous Face and Voice Processing: Electrophysiological Insights
(Public Library of Science, 2012)
Both facial expression and tone of voice represent key signals of emotional communication but their brain processing correlates remain unclear. Accordingly, we constructed a novel implicit emotion recognition task consisting ...
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 ...
Increased diffusivity in superior temporal gyrus in patients with schizophrenia: A Diffusion Tensor Imaging study
(Elsevier BV, 2009)
Background: Superior temporal gyrus (STG) volume reduction is one of the most consistent findings in schizophrenia. The goal of this study was to conduct the first diffusion tensor imaging (DTI) study to investigate altered ...
