Dopaminergic mechanisms supporting hippocampal postencoding dynamics in humans.
Article in Proceedings of the National Academy of Sciences of the United States of America, 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
Deficits in dopamine function cause alterations in episodic memory. Converging evidence implicates dopamine in postencoding hippocampal mechanisms inferred to support long-term memory, though there is a lack of direct evidence in humans. We address this gap using pharmacological functional MRI (fMRI) and positron emission tomography (PET). Using a motivated reward encoding task on and off oral methylphenidate, we tested whether individual differences in baseline dopamine ([
