ABSTRACT
OBJECTS This study was designed to make a comparison between methods to determine the components of topographic auditory event related potential P300. METHODS:
The subjects were consisted of 44 normal controls and 44 patients with schizophrenia diagnosed by DSM-IV. The topographic auditory event related P300 was recorded in oddball paradigm. The components of P300, including latency, amplitude, and location of maximum amplitude in X-Y coordinates, were analized by computerized EP mapping system. The latency of P300 was determined by both global field power measurement and classic method.RESULTS:
There was difference between two groups in latency(DF=1, F=35.28, P= 0.0001) and amplitude(DF=1, F=36.62, P=0.0001), but not in X coordinate(DF=1, F=0.37, P=0.55) and Y coordinate(DF=1, F=2.00, P=0.16). There was no difference between two mothods in latency(DF=1, F=0.04, P=0.85), in amplitude(DF=1, F=0.07, P=0.79), in X coordinate(DF=1, F=0.07, P=0.79), and in Y coordinate(DF=1, F=0.03, P=0.86).CONCLUSION:
The results suggested that two methods to determine the components of topographic auditory event related potential P300 should be available for both research and clinical application to date.
