Alpha oscillations mediate inhibitory control and perceptual transitions during binocular rivalry
Bibliographic record
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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
