Backward alpha band oscillations shape perceptual bias under probabilistic cues.
Article in Communications biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Predictive coding theory suggests that prior knowledge is crucial for optimizing human decision-making. However, how cortical dynamics implement this integration remains unclear. Here, we employ a traveling wave approach to investigate how alpha band oscillations integrate prior expectations during a perceptual decision-making task. Our findings demonstrate that expectation-based knowledge triggers the propagation of alpha band traveling waves from frontal to occipital areas, with this increase associated with enhanced modulation of brain regions involved in stimulus processing and directly linked to prior-driven bias at the behavioral level. Moreover, participants who rely more on prior expectations exhibit stronger top-down signaling (frontal-to-occipital), whereas those who focus on sensory input show a contrasting bottom-up pattern (occipital-to-frontal). These results highlight the role of alpha band traveling waves in predictive mechanisms, suggesting that rhythmic interactions across brain regions facilitate this process and contribute to inter-individual differences in its implementation.
