The lateralized LC-NAergic system distinguishes vicarious versus direct fear in mice.
Article in Nature communications, 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
Fear can be induced either directly through self-experience of aversive events or vicariously by observing conspecifics experiencing such events. The locus coeruleus-norepinephrine (LC-NA) system is crucial in fear responses and cognitive processes. We investigated whether the LC-NA system differentially processes these two types of fear, direct and vicarious in male mice. The results highlighted that the right hemisphere LC→anterior cingulate cortex pathway is uniquely crucial for vicarious fear, while the two inputs to the LC-from the bed nucleus of the stria terminalis (BNST) and the central amygdala (CeA)-differentially contribute to fear processing. The BNST plays a more targeted role in vicarious fear, and the CeA has a broader influence on fear in general. This underscores the complexity and specialization within the LC-NA system for fear-processing.
