Event-related potential

Event-related potentials (ERPs) are measured brain responses that are directly the result of a specific sensory, cognitive, or motor event. They are obtained through electroencephalography (EEG), which records electrical activity in the brain via electrodes placed on the scalp. ERPs reflect the time-locked brain activity following the presentation of a stimulus, such as visual or auditory information, and can be used to study a variety of cognitive processes, including perception, attention, memory, and decision-making.
