Neuropsychological Correlates of Diffusion Tensor Imaging in Schizophrenia.
(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 ...
A diffusion tensor imaging study of the anterior limb of the internal capsule in schizophrenia
(Elsevier BV, 2010)
Introduction—Frontal-subcortical cognitive and limbic feedback loops modulate higher cognitive functioning. The final step in these feedback loops is the thalamo-cortical projection through the anterior limb of the internal ...
Identification of neural circuits underlying P300 abnormalities in schizophrenia
(Wiley-Blackwell, 1999)
Event-related potentials (ERPs) provide a noninvasive method to evaluate neural activation and cognitive processes in schizophrenia. The pathophysiological significance of these findings would be greatly enhanced if ...
Spatial Frequency Discrimination in Schizophrenia
(American Psychological Association (APA), 2002)
Pathways within the visual system can be distinguished on the basis of selectivity for low or high spatial frequencies. Spatial frequency discrimination was evaluated in 17 medicated male patients with schizophrenia and ...
Event-related potentials elicited during a context-free homograph task in normal versus schizophrenic subjects
(Wiley-Blackwell, 2000)
Thought disorder in schizophrenia may involve abnormal semantic activation or faulty working memory maintenance. Event-related potentials (ERPs) were recorded while sentences reading “THE NOUN WAS ADJECTIVE/VERB” were ...
An fMRI study of semantic processing in men with schizophrenia
(Elsevier BV, 2003)
As a means toward understanding the neural bases of schizophrenic thought disturbance, we examined brain activation patterns in response to semantically and superficially encoded words in patients with schizophrenia. Nine ...
Diffusion tractography of the fornix in schizophrenia
(Elsevier BV, 2009)
Background: White matter fiber tracts, especially those interconnecting the frontal and temporal lobes, are likely implicated in pathophysiology of schizophrenia. Very few studies, however, have focused on the fornix, a ...
The role of retrieval inhibition in the associative memory impairment of schizophrenia
(Elsevier BV, 2007)
To examine retrieval-induced forgetting (RIF) in schizophrenia, subjects studied category-exemplar words taken from either strong or weak categories, and then practiced retrieval by completing category word-stems on half ...
DTI and MTR abnormalities in schizophrenia: Analysis of white matter integrity
(Elsevier BV, 2005)
Diffusion tensor imaging (DTI) studies in schizophrenia demonstrate lower anisotropic diffusion within white matter due either to loss of coherence of white matter fiber tracts, to changes in the number and/or density of ...
