A midbrain circuit for high-fat-food induced conditioned taste aversion.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Conditioned taste aversion (CTA) is a survival mechanism that prevents consumption of harmful foods. Yet its neural circuits, especially those for solid food aversion, are poorly understood. Using a male mouse model where high-fat food (HFF) was paired with LiCl injections, we identified the median raphe region (MRR) as essential for CTA. Optogenetic activation of MRR glutamatergic neurons replaced LiCl injections, inducing robust HFF aversion. Calcium signaling in MRR neurons increased upon HFF approach post-CTA. We uncovered a necessary glutamatergic projection from the medial preoptic area (MPOA) to the MRR; stimulating this circuit mimicked LiCl, to elicit HFF aversion. Following CTA, synaptic changes in MRR neurons included an increased mEPSC frequency and an altered paired-pulse ratio in the MPOA
