Event-related brain potentials (ERPs) to intact faces and to faces without eyes were compared to ERPs elicited by houses to find out whether the face-specific N170 component reflects the activity of a cortical eye processor. When compared to houses, face stimuli elicited a posterior negativity (N170) and a frontocentral positivity. N170 amplitude was not affected by the presence or absence of eyes, but N170 was delayed in response to faces without eyes. It is concluded that the N170 is not directly related to the activity of cortical regions sensitive to the presence of eyes, and is more likely to reflect processes involved in the structural encoding of face components.
将与完整面孔和无眼面孔相关的脑电活动（ERPs）与房屋引发的ERPs进行比较，以确定面孔特异性N170成分是否反映了皮质眼处理器的活动。与房屋相比，面孔刺激引发了后部负波（N170）和额中央正波。N170波幅不受眼睛有无的影响，但对无眼面孔的反应中N170出现延迟。得出的结论是，N170与对眼睛存在敏感的皮质区域的活动没有直接关系，更有可能反映参与面孔成分结构编码的过程。
