Local lateral connectivity is sufficient for replicating cortex-like topographical organization in deep neural networks.
Article in Nature communications, 2026. 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
Across the primate cortex, neurons with similar functions tend to cluster spatially, a principle that extends across many species and reflects a common strategy for organizing sensory processing. In the visual cortex, this appears as modular clusters tuned to specific visual features. Although short connections are widely believed to support such organization, the underlying neural mechanisms remain unclear. Here, we show that artificial deep neural networks develop topographic maps resembling those in primary, intermediate, and high-level human visual cortex when their units include local lateral connections and are trained through standard top-down credit assignment. Notably, this modular organization emerges without any explicitly imposed topography-inducing objectives or learning rules, suggesting that local lateral connections alone can drive the formation of cortical-like maps. Incorporating such lateral connections also improves model robustness to subtle, adversarial perturbations, highlighting an additional computational role for local recurrent structure in shaping robust visual representations.
