Cocaine seeking and consumption are oppositely regulated by mesolimbic dopamine in male rats.
Article in Nature communications, 2025. 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
Drug-associated stimuli (cues) can usurp potent control of behavior in individuals with substance use disorders; and these effects are often attributed to altered dopamine transmission. However, there is much debate over the way in which dopamine signaling changes over the course of chronic drug use. Here, we carried out longitudinal recording and manipulation of cue-evoked dopamine release in the core of the nucleus accumbens across phases of substance use in male rats. We show that, in a subset of individuals that exhibit increased cue reactivity and escalated drug consumption, this signaling undergoes diametrically opposed changes in amplitude, determined by the context in which the cue was presented. Dopamine evoked by non-contingent cue presentation (independent of the animal's actions) increases over drug use, producing greater cue reactivity; whereas dopamine evoked by contingent cue presentation (dependent on the animal's actions) decreases over drug use, producing escalation of drug consumption. Therefore, despite being in opposite directions, these dopamine trajectories each promote cardinal features of substance use disorders.
