Visual awareness sharpens and accelerates attentional sampling through enhancing inhibitory neural modulation in the attention network.

ABSTRACT: Attentional sampling, orchestrated by neural oscillations within the frontoparietal attention network, sequentially focuses on stimuli in a dynamic pattern, thereby enhancing the efficiency of attentional selection. However, the role of conscious awareness in this default attentional process remains largely unexplored. Here, we employed the Chromatic Flicker Fusion (CFF) method to render attentional cues invisible and investigated how cue awareness modulates attentional sampling. Using a high-temporal-resolution behavioral paradigm and electroencephalography (EEG) combined with the temporal response function (TRF) approach, we found that both visible and invisible cues induced rhythmic behavioral sampling and reset connectivity between the frontal and right occipito-parietal regions, indic
