ERP abnormalities during semantic processing in schizophrenia.

TL;DR: The study of environmental factors in schizophrenia may have important implications for the identification of causes and prevention of this disorder, and offers the potential to complement, and refine, existing efforts on explanatory neurodevelopmental models.

TL;DR: The literature on disease-liability associated variants in structural and functional magnetic resonance images, sensory processing measures, neuromotor abilities, neuropsychological measures, and physical characteristics in schizophrenia patients, their first-degree relatives, and healthy controls is reviewed.

TL;DR: A neo-Bleulerian approach to the assessment of communication disorders that is critical to the improvement of schizophrenic disorganization's clinical description is proposed.

TL;DR: This article found that sentence context has a dramatic effect on single-word processing, and that high and low-frequency words elicit different ERPs at the beginning of sentences but this effect is suppressed by a meaningful sentence context.

TL;DR: In a sentence reading task, words that occurred out of context were associated with specific types of event-related brain potentials that elicited a late negative wave (N400).

TL;DR: The amplitude of the N400 component of the e.r.p.ps was found to be an inverse function of the subject's expectancy for the terminal word as measured by its ‘Cloze probability’, which suggests N400 may reflect processes of semantic priming or activation.

TL;DR: The selection of instructions for subjects, the recording technique, the elimination of a few single trials significantly contaminated by eye movements, and the use of a correction procedure for ocular artifacts with calculable reliability and validity resulted in a set of data, in which 94% of the single trials were suitable for further analysis.

TL;DR: Using potential distributions generated by dipole sources in spherical volume conductor models, it is demonstrated that highly significant interactions involving electrode location can be obtained between scalp distributions with identical shapes generated by the same source.
