Dopamine modulation of motor and implicit learning contributions to auditory temporal attention.
Article in iScience, 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
Auditory periodic temporal attention operates optimally around 1.5 Hz when temporal structure is judged explicitly. Synchronized rhythmic movements further enhance its efficacy, an effect thought to depend on basal ganglia dopamine, crucial for both motor and temporal processing. However, whether dopamine underpins the relationship between auditory temporal attention and motor activity remains unclear. Using an auditory temporal attention task in Parkinson's disease (PD) patients ON versus OFF the dopaminergic medication L-DOPA, alongside healthy controls, we found no evidence that dopamine modulates the ∼1.5 Hz optimal sampling rate of auditory temporal attention. However, dopamine enables motor synchronization to the auditory stream and is hence crucial for the motor benefits of auditory temporal attention. Performing the first session ON L-DOPA also improved performance in the following session. These findings underscore a selective role for dopamine in audio-motor interaction, with no evidence that the intrinsic rhythm of auditory attention depends on dopamine.
