Synchronization of behavioral and cardiac dynamics in larval zebrafish.
Article in Cell reports, 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
Animals reprioritize behavioral goals in response to internal physiological states. Using larval zebrafish, we investigated whether engagement with a visuomotor task, the optomotor response (OMR), is coupled to cardiac dynamics. We discovered that threats lead to tachycardia that is synchronized with behavioral suppression. The change in heart rate is represented in the activity of specific neuronal populations. Severing the input to the sympathetic ganglia or ablating the vagus nerve revealed that the threat-related changes to behavioral state do not require interoceptive pathways. Direct tachycardic optopacing of the heart similarly suppressed the OMR response, but by reducing cardiac filling during diastole, thereby impacting oxygen delivery to the CNS. Optopacing also changed the activity of specific brain regions but in neurons distinct from those associated with threat-induced tachycardia. These cardiac function-associated central changes may have relevance to autonomic imbalances in anxiety, stress, and orthostatic disorders.
