Nurr1 Orchestrates Claustrum Development and Functionality.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2026. 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
Claustrum is the part of the forebrain known to be most widely interconnected tissue with almost all brain regions. It is believed to be involved in coordinating multiple cognitive behaviors including consciousness formation. However, little is known about the molecular mechanisms underlying its development and involvement in behavioral control. Here we show that Nurr1 (Nr4a2) is the key transcription factor orchestrating claustral morphogenesis, cell fate specification, connectivity and thus behaviors. Nurr1-deficient claustral cells aberrantly migrate into insular cortex, shaping claustrum from a crescent-like into a wing-like structure. These cells ectopically turn on insular cortex genetic programs that were verified by single cell transcriptomics. Accordingly, functional connectivity of the claustrum is not properly formed and relevant behaviors are dysregulated in Nurr1-deficient mice. Additionally, we show that Nurr1 regulates claustral neuron positioning and cell fate by suppressing Gαs-PKA signaling.
