Protocol for designing, conducting, and analyzing event-related potentials in human participants

Event-related potentials (ERPs), measured using electroencephalography (EEG), are electrical brain potentials related to specific events, such as the presentation of visual stimuli. In this protocol, we describe steps for designing an ERP experimental task, measuring EEG, preprocessing EEG data in MATLAB, and exporting ERP data for statistical analyses. This protocol is intended to be applicable to common ERP experiments in cognitive neuroscience. For complete details on the use and execution of this protocol, please refer to Pütz and colleagues.¹.
