- Prefrontal Cortical Thickness in First-Episode Psychosis: A Magnetic Resonance Imaging Study
- Findings from postmortem studies suggest reduced prefrontal cortical thickness in schizophrenia; however, cortical thickness in first-episode schizophrenia has not been evaluated using magnetic resonance imaging MRI. This paper demonstrates the potential usefulness of MRI for the study of cortical thickness abnormalities in schizophrenia. Correlations between cortical thickness and age and...

- Shape of Caudate Nucleus and Its Cognitive Correlates in Neuroleptic-Naive Schizotypal Personality Disorder
- This paper measures the shape of the head of the caudate nucleus with a new approach based on magnetic resonance imaging MRI in schizotypal personality disorder SPD subjects in whom it previously reported decreased caudate nucleus volume. It was believed MRI shape analysis complements traditional MRI volume measurements. These data...

- Cingulate Fasciculus Integrity Disruption in Schizophrenia: A Magnetic Resonance Diffusion Tensor Imaging Study
- 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, the white matter tract furnishing both input and output to CG, and the most prominent white matter fiber tract...

- The P3 Auditory Event-Related Brain Potential Indexes Major Personality Traits
- The amplitude of the auditory P3 event-related potential is reduced in patients with axes I and II disorders. Data regarding P3 amplitude and normal personality traits in healthy individuals have been inconsistent, however, although more extreme variants of dimensional traits such as neuroticism and extraversion are associated with psychiatric morbidity....

- Lateralized P3 Deficit in Schizotypal Personality Disorder
- Reduced, left-lateralized P3 amplitude has been reported in several studies focusing on electrophysiologic function in schizophrenia. Also, several lines of evidence suggest a similarity between schizophrenia and schizotypal personality disorder SPD. This paper was undertaken to determine the replicability of the previous finding of a left-lateralized P3 amplitude deficit in...
