Ventral hippocampus neurons encode meal-related memory.
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 11 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
The ability to encode and retrieve meal-related information is critical to efficiently guide energy acquisition and consumption, yet the underlying neural processes remain elusive. Here we reveal that ventral hippocampus (HPCv) neuronal activity dynamically elevates between eating bouts during meal consumption and this response is predictive of performance in a foraging-related memory test for the spatial location of a previously consumed meal. Targeted recombination-mediated ablation of HPCv meal-responsive neurons impairs meal location memory without influencing food motivation or spatial memory for escape location. These HPCv meal-responsive neurons project to the lateral hypothalamic area (LHA) and are enriched in serotonin 2a receptors (5HT2aR). Either chemogenetic silencing of HPCv-to-LHA projections or intra-HPCv 5HT2aR antagonist yielded meal location memory deficits, as well as increased caloric intake driven by shorter temporal intervals between meals. Collective results identify a population of HPCv neurons in male rats that dynamically respond during eating to encode meal-related memories.
