Enhancing Human Action Inhibition Through Cortico-Cortical Paired Associative Stimulation.
Article in Annals of the New York Academy of Sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Reactive inhibition is crucial for preventing inappropriate actions, and impairments in this ability are common in various disorders, with the underlying neural mechanisms poorly understood. To explore the neural dynamics of such an ability, we used a novel transcranial magnetic stimulation (TMS) protocol, cortico-cortical paired associative stimulation (ccPAS), to induce Hebbian spike-timing-dependent plasticity (STDP). Our goal was to investigate the functional relevance of key brain regions in the action inhibition network (AIN). Healthy participants underwent ccPAS targeting functional connectivity between AIN regions: pre/supplementary motor area (preSMA/SMA) to the left motor cortex (lM1), right inferior frontal gyrus (rIFG) to lM1, or right M1 (rM1) to lM1. Participants completed a stop signal task (SST) before and after ccPAS stimulation. Motor evoked potentials (MEP) were recorded during ccPAS to assess network plasticity, and resting motor threshold (rMT) was measured for global motor excitability. Reactive inhibition improved selectively in the preSMA/SMA-lM1 group, with MEPs increasing after preSMA/SMA-lM1 and rM1-lM1 stimulation, suggesting facilitatory modulations. rMT correlated with behavioral improvement in the preSMA/SMA group. These findings demonstrate that ccPAS improved reactive inhibition, enhancing plasticity between preSMA/SMA and lM1, providing insights into the AIN's functional mechanism.
