2. Event-related potential - Wikipedia

   en.wikipedia.org/wiki/Event-related_potential

   This noise obscures the signal of interest, which is the sequence of underlying ERPs under study. From an engineering point of view it is possible to define the signal-to-noise ratio (SNR) of the recorded ERPs. Averaging increases the SNR of the recorded ERPs making them discernible and allowing for their interpretation.

3. Error-related negativity - Wikipedia

   en.wikipedia.org/wiki/Error-related_negativity

   The ERN is a sharp negative going signal which begins about the same time an incorrect motor response begins, (response locked event-related potential), and typically peaks from 80 to 150 milliseconds (ms) after the erroneous response begins (or 40–80 ms after the onset of electromyographic activity).

4. C1 and P1 - Wikipedia

   en.wikipedia.org/wiki/C1_and_P1

   Whereas previous papers had looked at human ERPs to visual stimuli, and, undoubtedly, recorded P1 components as can be seen by visually inspecting the waveforms in the early articles, [3] Spehlmann was one of the first to describe a "surface positive component at 80-120ms." In his experiment, Spehlmann showed participants patterns of black and ...

5. N200 (neuroscience) - Wikipedia

   en.wikipedia.org/wiki/N200_(neuroscience)

   An ERP can be monitored using a non-invasive electroencephalography 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 in neurons, which fluctuate in relation to cognitive processing.

6. Visual N1 - Wikipedia

   en.wikipedia.org/wiki/Visual_N1

   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

7. P600 (neuroscience) - Wikipedia

   en.wikipedia.org/wiki/P600_(neuroscience)

   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.
