1 · What the graph read from it

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.

2 · The registry

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

Brain architectures vary widely across species, yet how neuronal positioning constrains the type of circuits that can be made, and their function, remains poorly understood. Here we examine how neuronal position affects molecular identity, connectivity and function by studying Eml1 knockout mice, which exhibit abnormally located (heterotopic) neurons beneath the cortex. Heterotopic neurons maintained their molecular signatures, formed appropriate long-range connections and exhibited coherent electrophysiological properties. They organized into functional sensory-processing centers that mirrored their cortical counterparts, with preserved somatotopic mapping and responsiveness to sensory stimuli. Remarkably, cortical silencing did not impair sensory discrimination, revealing that heterotopic neurons were the main drivers of this function. Hence, equivalent circuits can emerge in different spatial configurations, allowing diverse brain architectures to converge on similar functional outcomes.
