Mapping Brain Spatial Metabolic Atlas Reveals Anesthesia-Induced Region-Specific Alterations.
Article in Neuroscience bulletin, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 brain supports consciousness through regional heterogeneity. However, the spatial complexity of its metabolome under anesthesia remains unclear. In this study, we established a spatial metabolomic atlas of the mouse brain under wakefulness, inhalation anesthesia, and injectable anesthesia. In total, 727 metabolites were identified and spatially mapped across 11 representative brain regions. We found that anesthesia significantly altered the brain metabolic landscape in a spatially dependent manner, particularly affecting lipid metabolism, amino acid pathways, and neurotransmitter-related metabolites. Furthermore, we monitored the cortical microvascular blood flow and blood oxygen levels during anesthesia. We observed that different anesthesia modalities induced distinct changes in cortical arteriovenous microvascular hemodynamics, suggesting a potential association between metabolic alterations and cerebrovascular regulation. We developed an open-access online database, the mouse brain spatial metabolome atlas ( https://mbsma.liulab.cloud/#/dashboard ), to facilitate access to and analysis of the dataset. Our study reveals anesthesia-induced spatial metabolic reprogramming in the brain, providing insights into neural metabolism and cerebrovascular dynamics, with implications for perioperative brain protection and safer anesthesia strategies.
