Dose-related effects of ethanol on visual sustained attention and event-related potentials.
Among the novel tools for experimental analysis of cognitive function, averaged time-locked event-related potentials (ERPs) have been widely studied.
The waveforms of the event-related potentials (ERPs) revealed topographical differences in the N400 amplitude, a component that appears to be associated with the processing of semantic incongruity (Kutas & Federmeier, 2000; Kutas & Hillyard, 1980) and the retrieval of semantic memory (Herzmann & Sommer, 2007; Kutas & Federmeier, 2000).
Modulated microwave effects on electroencephalographic event-related potentials (ERP) and cognitive performance has been the subject of extensive discussion during the last decade.

The purpose of this study is to research the brain dynamics of cognitively normal PD patients and healthy elderly controls using event-related potentials (ERPs) and to evaluate their relationships with neuropsychological tests.
Informed consent was obtained, and all participants completed a battery of self-report measures as part of a larger study and event-related potential (ERP) tasks; the experimental session lasted approximately 3 hours and was followed by debriefing.
