Button-pressing affects P300 amplitude and scalp topography
(Elsevier BV, 2001)
Background: Scant and equivocal research exists examining the effects of button-pressing on P300. Button-pressing may decrease P300 latency and amplitude. The melding of motor potentials and P300 may also confound studies ...
ERP abnormalities during semantic processing in schizophrenia
(Elsevier BV, 1993)
To examine the neurophysiological and cognitive characteristics of thought disturbance in schizophrenic patients, we examined the amplitude, latency, and topography of a specific event-related brain potential (ERP), the ...
Processing sentence context in women with schizotypal personality disorder: An ERP study
(Wiley-Blackwell, 2004)
Accumulating evidence suggests that schizophrenic patients do not use context efficiently. Also, studies suggest similarities in clinical and cognitive profiles between schizophrenic and schizotypal personality disorder ...
The NoGo P300 ‘anteriorization’ effect and response inhibition
(Elsevier BV, 2004)
Objective: The P300 event-related potential shows anterior P300 increases on NoGo tasks (target stimulus = withhold response) relative to Go tasks (target stimulus = commit response). This `NoGo anteriorization' has been ...
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 ...
