摘要

Almost ten years ago, Kelly and collegues reported that the earliest component (i.e., the C1) of the visual evoked potential (VEP) could be modulated by spatial attention. Using a similar experimental design and data analysis methods, however, Baumgartner et al. (this issue) recently failed to provide confirmative evidence. In this commentary, I suggest that some minor differences in experimental design may account for the inconsistent results between the two studies. I also propose a hypothesis that the C1 effect reported in Kelly et al. may not necessarily reflect modulations of the initial visual evoked response in human V1.
