Structural and genetic determinants of zebrafish functional brain networks.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Network science has revealed universal brain connectivity principles across species. However, several macroscopic network features established in human neuroimaging studies remain underexplored at cellular scales in small animal models. Here, we use whole-brain calcium imaging in larval zebrafish to investigate the structural and genetic basis of functional brain networks. Mesoscopic functional connectivity (FC) robustly captures the individuality of larvae and reflects structural connectivity (SC) derived from single-neuron reconstructions. Several connectome properties, including diffusion mechanisms and indirect pathways, predict interregional correlations. SC and FC share a hierarchical modular architecture, with structural modules shaping spontaneous and stimulus-driven activity patterns. Visual stimuli and tail monitoring reveal a functional gradient that coincides with sensorimotor functions. Last, regional expression levels of specific genes predict interregional FC. Our findings reproduce key mammalian brain network features, demonstrating larval zebrafish as a powerful model for studying large-scale network phenomena in a small and optically accessible vertebrate brain.
