eLife Assessment
In this study, electroencephalography was recorded during a binocular-rivalry paradigm in which participants viewed a target and a distractor stimulus. The stimuli were independently frequency-tagged, allowing the researchers to track target and distractor processing over time. The findings suggest that parietal alpha oscillations initially segregate competing inputs, followed by frontal theta activity associated with suppression of distractor representations. The significance of these findings is valuable, although the strength of the evidence remains incomplete, because of specific experiment design choices and methodological limitations.
