Optogenetic interrogation of the zebrafish lateral line reveals brain-wide neural circuits involved in pattern separation.
Article in iScience, 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
An animal's ability to interact with its environment relies on the brain's capacity to distinguish between patterns of sensory information. To investigate this, we used the posterior lateral line system of larval zebrafish, composed of mechanosensory neuromasts innervated by neurons from the posterior lateral line ganglion. Using single-neuromast optogenetic stimulation and whole-brain calcium imaging, we developed a precise and flexible approach to examine sensory processing. Stimulating individual neuromasts revealed that second-order circuits show diverse selectivity despite lacking topographic organization. We further show that complex combinations of neuromast stimulation are encoded by sparse neuronal ensembles within the medial octavolateralis nucleus (MON) and that neuromast input integrates nonlinearly. This approach provides a powerful method for spatiotemporal interrogation of the zebrafish lateral line, sheds light on how neuromast input is integrated in the brain, and positions this system as a valuable model for studying whole-brain sensory encoding.
