Alpha oscillations mediate inhibitory control and perceptual transitions during binocular rivalry.
Article in iScience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Binocular rivalry is a visual phenomenon that involves alternating percepts despite stable input, providing a window into perceptual processing and neural dynamics. We examined changes in alpha band activity (8-13 Hz) using magnetoencephalographic imaging (MEG). Our time-frequency analysis demonstrates a decrease in alpha band power before the onset of rivalry alternations, indicating a reduction in inhibitory processing, permitting destabilization of the dominant percept. In contrast, an increase in alpha power was observed prior to participant's report of mixed percepts, suggesting heightened inhibitory processing associated with perceptual ambiguity. Directed connectivity analysis (phase transfer entropy) revealed enhanced feedback connectivity from parietal to early visual areas preceding perceptual dominance, which shifted toward feedforward connectivity following perceptual alternations. These findings suggest that alpha oscillations play a critical role in the excitation-inhibition balance that underlies perceptual stability during binocular rivalry and are further related to individual differences in perceptual experiences.
