Abstract

Slotnick (this issue) has specified a number of experimental parameters that appear critical for enabling an attention-related modulation of the C1 component. These include stimulus presentation in the upper visual field, the presence of distractors, a high perceptual or attentional load, and measurements at midline occipito-parietal sites. While we agree with many of these recommendations, we would modify others and even dispute a few. Despite the employment of these parameters in a few existing studies, there has not yet been a convincing, reproducible demonstration of a modulation of the C1 component by spatial attention that can be localized to primary visual cortex.
