Error-related negativity
From Wikipedia, the free encyclopedia
Error-related negativity (ERN), sometimes referred to as the Ne, is a component of an event-related potential (ERP). ERPs are electrical activity in the brain as measured through electroencephalography (EEG) and time-locked to an external event (e.g., presentation of a visual stimulus) or a response (e.g. an error of commission). A robust ERN component is observed after errors are committed during various choice tasks, even when the participant is not explicitly aware of making the error;[1] however, in the case of unconscious errors the ERN is reduced.[2][3] An ERN is also observed when non-human primates commit errors.[4]
