ERPs reflect brain activity time-locked to events, such as stimuli and/or tasks. After recording the voltage differences on the scalp caused by the electric current in neurons (i.e., the EEG), ERPs are extracted by averaging those parts of the EEG that occur during the stimuli/tasks. This averages out neural oscillations and noise and leaves the electrical activity elicited by the stimulus and/or task. The main advantages of ERPs are that they have a temporal resolution in the order of milliseconds and that they provide information about cognitive processes [44,45]. The ERP consists of different components, each of which has a certain polarity, latency, and scalp topography, and reflects a cognitive process. <Electrophysiological Correlates of Romantic Love: A Review of

EERP (Earliy)
The N170 is a negative peak around 170 ms over the lateral posterior scalp that reflects
structural face encoding
Although there was no evidence that the N170
differs between boyfriend, father, stranger, and baby pictures
