Perceptual Bias in Motion Discrimination is Related to Asymmetric Interhemispheric Alpha Traveling Waves.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Perception relies on hierarchical processes integrating sensory data into higher-order models about the world. In the sensory domain, this hierarchy also involves horizontal pathways aiding interhemispheric interactions. For example, recent focus on the V5-V5 network revealed its role in motion processing. However, despite converging evidence demonstrating the crucial role of oscillatory activity in inter-areas communication, the specific rhythmic code governing V5-V5 interaction is unclear. Through traveling wave analysis, this gap is filled by identifying the alpha/low-beta frequency (9-16 Hz) as crucial for long-range, interhemispheric communication between V5 regions. Notably, a pronounced imbalance is observed: stronger waves travelled in the left-to-right-V5 direction. Crucially, this observation extends to the behavioural level, as Signal Detection Theory analysis uncovered a correlation between the highlighted imbalance and a perceptual bias favouring leftward motion reporting. Our findings underscore asymmetrical projections between V5 regions, highlighting the interplay between inter-hemispheric traveling wave patterns in dictating motion perception.
