Reduced Adult Neurogenesis in Humans Results From a Tradeoff Rather Than Direct Negative Selection.
Review in BioEssays : news and reviews in molecular, cellular and developmental biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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 reduction of adult neurogenesis in the human brain, compared to other vertebrate species, has been proposed to result from an active counter-selection to permit the stability of circuits needed for long-term memorization and higher cognitive abilities. Here, bringing forward behavior studies and evolution-based observations, we discuss the benefits of adult neurogenesis and data suggesting that its loss is unlinked with cognitive levels. Considering cell lineages and functional assays, we further note that human-specific genomic features (such as novel gene variants or regulatory sequences) frequently hit pathways that may lead to the premature exhaustion of embryonic neural progenitors after the developmental phase of cortex formation. We propose that reduced adult neurogenesis in humans may be a tradeoff for these changes, themselves selected for to permit the enlargement and complexification of the cerebral cortex during development.
