Natural variations in maternal behavior shape anxiety and hippocampal neurogenesis in offspring.

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
Understanding the mechanisms of individualization of emotional traits is crucial for the development of personalized medicine in mood disorders. Although previous research focused on genetic differences or experimental manipulations of maternal care, it is unclear whether natural variations in maternal care in the absence of genetic variability influence anxiety-related behavior and neurogenesis. We addressed this question by observing inbred mouse maternal care and offspring in a longitudinal manner. We found that mothers spontaneously displaying low maternal care showed lower adult neurogenesis in both the olfactory bulb and the hippocampus compared with high maternal care mothers. In turn, low maternal care-reared pups exhibited increased anxiety as compared to high maternal care-reared pups, which was associated with decreased postnatal neurogenesis after weaning. These results highlight that in the absence of genetic diversity, natural variations in early-life experience are sufficient to shape brain plasticity and anxiety-related behavior in offspring. This underscores the relevance of maternal care and hippocampal neurogenesis in shaping personality-like traits related to mood disorders and inducing emotional individuality in early stages of life.
