Non-uniform contextual interactions in the visual cortex place fundamental limits on spatial vision.
Article in Cell reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
A common assumption is that contextual integration in the primary visual cortex (V1) is spatially uniform. However, perceptual phenomena such as visual crowding reveal non-uniform interactions, with flankers at specific geometries exerting stronger effects. To resolve this discrepancy, we investigated how flanker geometry impacted the representation of a target stimulus in the laminar microcircuits of V1. Our study indicates that flanker location differentially impairs stimulus representation in excitatory neurons in the superficial and input layers of V1 through tuned suppression and untuned facilitation of orientation responses. Mechanistically, this effect can be explained by asymmetrical spatial kernels in a normalization model of cortical activity. Strikingly, these non-uniform modulations of neural representation mirror perceptual anisotropies. These results demonstrate that the non-uniform spatial integration of information in the earliest stages of cortical processing places a fundamental limit on spatial vision.
