Activated glutamatergic neurons in basolateral amygdala suppress nicotine preference behavior in mice.
Article in Frontiers in pharmacology, 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
Despite the knowledge of the health risks of smoking, exposure to nicotine leads to smoking habits. Clarifying the neuronal mechanism of smoking preference formation underlying the development of smoking habits has a great impact on the establishment of effective smoking cessation therapies. In this study, the brain regions that determine the preference for oral nicotine intake in the two-bottle test were investigated. The activity of glutamatergic neurons reduced in the basolateral amygdala (BLA) of mice with a high preference for nicotine. Chemogenetic activation of glutamatergic neurons in the BLA decreased nicotine intake preference. These results indicate that glutamatergic neurons in the BLA modulate the preference for nicotine. This study presents a potential treatment strategy for smoking cessation that involves regulating the activity of glutamatergic neurons in the BLA.
