    • Association Between Reduced Extraversion and Right Posterior Fusiform Gyrus Gray Matter Reduction in Chronic Schizophrenia 

      Onitsuka, Toshiaki; Nestor, Paul Gerard; Gurrera, Ronald Joseph; Shenton, Martha Elizabeth; Kasai, Kiyoto; Frumin, Melissa; Niznikiewicz, Margaret A.; McCarley, Robert William (American Psychiatric Publishing, 2005)
      Objective: The authors examined the association between volume of the fusiform gyrus, a region involved in face processing, and the personality trait of extraversion in patients with schizophrenia. Method: Male patients ...

    • Dissociable contributions of MRI volume reductions of superior temporal and fusiform gyri to symptoms and neuropsychology in schizophrenia 

      Nestor, Paul Gerard; Onitsuka, Toshiaki; Gurrera, Ronald Joseph; Niznikiewicz, Margaret A.; Frumin, Melissa; Shenton, Martha Elizabeth; McCarley, Robert William (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, ...

    • The five-factor model in schizotypal personality disorder 

      Gurrera, Ronald Joseph; Dickey, Chandlee C.; Niznikiewicz, Margaret A.; Voglmaier, Martina M.; Shenton, Martha Elizabeth; McCarley, Robert William (Elsevier BV, 2005)
      Studies of the five-factor model of personality in schizotypal personality disorder (SPD) have produced inconsistent results, particularly with respect to openness. In the present study, the NEO-FFI was used to measure ...

    • Neuropsychological Correlates of Diffusion Tensor Imaging in Schizophrenia. 

      Nestor, Paul Gerard; Kubicki, Marek R.; Gurrera, Ronald Joseph; Niznikiewicz, Margaret A.; Frumin, Melissa; McCarley, Robert William; Shenton, Martha Elizabeth (American Psychological Association (APA), 2004)
      Patients with schizophrenia (n = 41) and healthy comparison participants (n = 46) completed neuropsychological measures of intelligence, memory, and executive function. A subset of each group also completed magnetic resonance ...

    • Neuropsychological disturbance in schizophrenia: A diffusion tensor imaging study. 

      Nestor, Paul Gerard; Kubicki, Marek R.; Niznikiewicz, Margaret A.; Gurrera, Ronald Joseph; McCarley, Robert William; Shenton, Martha Elizabeth (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) ...

    • The uncinate fasciculus and extraversion in schizotypal personality disorder: A diffusion tensor imaging study 

      Gurrera, Ronald Joseph; NAKAMURA, M; Kubicki, Marek R.; Dickey, Chandlee C.; Niznikiewicz, Margaret A.; Voglmaier, Martina M.; Seidman, Larry Joel; Westin, Carl-Fredrik; Maier, Stephan Ernst; McCarley, Robert William; Shenton, Martha Elizabeth (Elsevier BV, 2007)
