Evolutionary changes leading to efficient glymphatic circulation in the mammalian brain.
Article in Nature communications, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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 functional significance of the morphological and genetic changes that occurred in the brain during evolution is not fully understood. Here we show the relationships between evolutionary changes of the brain and glymphatic circulation. We establish a mathematical model to simulate glymphatic circulation in the cerebral hemispheres, and our results show that cortical neurons accumulate in areas of the cerebral hemispheres where glymphatic circulation is highly efficient. We also find that cortical folds markedly enhance the efficiency of glymphatic circulation in the cerebral hemispheres. Furthermore, our in vivo study using ferrets reveals sulcus-dominant cerebrospinal fluid (CSF) influx, which enhances the efficiency of glymphatic circulation in the enlarged cerebral hemispheres of gyrencephalic brains. Sulcus-dominant CSF influx is mediated by preferential expression of aquaporin-4 in sulcal regions, and similar expression patterns of aquaporin-4 are also found in human cerebral hemispheres. These results indicate that evolutionary changes in the cerebral hemispheres are related to improved efficiency of glymphatic circulation. It seems plausible that the efficiency of glymphatic circulation is an important factor determining the evolutionary trajectory of the cerebral hemispheres.
