摘要：

Normal subjects passively; viewed an upright or inverted face or objects during recording of event-related potentials. Face inversion augmented N170 amplitude and latency in the temporal region, but only the latency in the parietal region. The same manipulation slowed down the onset of the P220 and caused disappearance of the N300. whereas none of these effects was seen after object inversion. item-specific processing or objects was observed. namely disappearance of the N190 and the appearance of a P170 wave in the left posterior hemisphere to one object but not the other. These results are concordant with the hypothesis of category-specific processing during the recognition of faces and objects.
