    • Age-related changes in the electrophysiological response to visual stimulus novelty: A topographical approach 

      Thomas, Kathleen M.; Nelson, Charles A. (Elsevier BV, 1996)
      The relationship of task relevance and stimulus probability to P300 morphology, latency and distribution was assessed. Eight year olds and adults completed visual oddball tasks of recognition memory with frequent non-target ...

    • Button-pressing affects P300 amplitude and scalp topography 

      Salisbury, Dean F; Rutherford, Bret; Shenton, Martha Elizabeth; McCarley, Robert William (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 ...

    • Identification of neural circuits underlying P300 abnormalities in schizophrenia 

      O'Donnell, Brian F.; McCarley, Robert William; Potts, Geoffrey F.; Salisbury, Dean F.; Nestor, Paul Gerard; Hirayasu, Yoshio; Niznikiewicz, Margaret A.; Barnard, John; Jen Shen, Zi; Weinstein, David M.; Bookstein, Fred L.; Shenton, Martha Elizabeth (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 ...

    • Lateralized P3 deficit in schizotypal personality disorder 

      Niznikiewicz, Margaret A.; Voglmaier, Martina M.; Shenton, Martha Elizabeth; Dickey, Chandlee C.; Seidman, Larry Joel; Teh, EngKeat; Van Rhoads, Richard; McCarley, Robert William (Elsevier BV, 2000)
      Background: 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 ...
