A vasopressin gate transforms social distress into caregiving.
Article in The Journal of clinical investigation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Another individual's distress can provoke withdrawal and avoidance behaviors, yet, in social species, it can also motivate approach and caregiving behavior. In this issue, Geng et al. identified a vasopressin-sensitive neuronal circuit that converts distress signals from a cagemate into caregiving-like behavior in mice. Using fiber photometry, electrophysiological recordings, and optogenetic activation to dissect this circuit, they showed that vasopressin neurons in the paraventricular hypothalamus recruit vasopressin 1a receptor-expressing (V1aR-expressing) neurons in the medial central amygdala, which engage the ventral tegmental area to promote allogrooming and injury-directed licking. The findings link emotional state matching, prosocial action, reinforcement, and stress relief, while raising important questions about circuit specificity, sex as a biological variable, and translation.
