Cognitive functions of the GPe.
Review in Trends in neurosciences, 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 globus pallidus externus (GPe) is a central nucleus in the basal ganglia. Although traditionally defined as a component of the basal ganglia's motor circuit, converging evidence from humans, rodents, and non-human primates has established the GPe as a key contributor to the cognitive control of behavior. In this role, the GPe dynamically regulates goal-directed behavior in response to changing environmental demands. In this review, we highlight recent studies demonstrating that the GPe encodes cue and action values, supports behavioral flexibility, and modulates attention, behavioral inhibition, and habit formation. The picture that emerges is of a nucleus that aligns behavior to internal goals by constraining, updating, and optimizing ongoing actions.
