Definition
Event-related brain potentials (ERPs) represent the synchronous activity of populations of cortical neurons measured at the scalp. This entry considers age-related differences in ERPs related to language, episodic memory, and outcome processing.
Overview
Event-related brain potentials (ERPs) represent the synchronized activity of populations of cortical neurons measured noninvasively at the scalp that are time-locked to some event of interest (e.g., the onset of a stimulus or a button press) (Luck and Kappenman 2012). ERPs provide excellent temporal resolution to examine the unfolding of information processing over time that is superior to hemodynamic measures such as functional magnetic resonance imaging (fMRI) or near-infrared spectroscopy (NIRS). In contrast, the spatial resolution of ERPs is inferior to that of fMRI, although distributed source analysis in combination with multivariate statistical techniques may provide a...
