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
A waveform showing several ERP components, including the N100 (labeled N1) and P300 (labeled P3). The ERP is plotted with negative voltages upward, a common, but not universal, practice in ERP research. An event-related potential (ERP) is the measured brain response that is the direct result of a specific sensory, cognitive, or motor event. [1]
Besides modulation by inversion and race, emotional expressions have also been a focus of N170 face research. In an experiment conducted by Righart and de Gelder, ERP results show that the early stages of face processing may be affected by emotional scenes when categorizations of fearful and happy facial expressions are made by subjects.

The C1 and P1 (also called the P100) are two human scalp-recorded event-related brain potential (event-related potential (ERP)) components, collected by means of a technique called electroencephalography (EEG). The C1 is named so because it was the first component in a series of components found to respond to visual stimuli when it was first ...
The amplitude, or the size, of the N1 is measured by taking the average voltage within the window that typically encompasses the N1 (about 150 to 200 ms post-stimulus).). Because the N1 is a negative-going component, "larger" amplitudes correspond to being more negative, whereas "smaller" amplitudes correspond to being less nega
The N200, or N2, is an event-related potential (ERP) component. An ERP can be monitored using a non-invasive electroencephalography (EEG) cap that is fitted over the scalp on human subjects. An EEG cap allows researchers and clinicians to monitor the minute electrical activity that reaches the surface of the scalp from post-synaptic potentials ...
The P600 is an event-related potential (ERP) component, or peak in electrical brain activity measured by electroencephalography (EEG). It is a language-relevant ERP component and is thought to be elicited by hearing or reading grammatical errors and other syntactic anomalies.
The mismatch negativity (MMN) or mismatch field (MMF) is a component of the event-related potential (ERP) to an odd stimulus in a sequence of stimuli. It arises from electrical activity in the brain and is studied within the field of cognitive neuroscience and psychology.
