Integrating computational modeling, neuroimaging, and neuromodulation to decompose perceptual decision-making in healthy aging: a review of methods, findings, and gaps.
Review in Frontiers in aging neuroscience, 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
Perceptual decision-making (PDM) - the transformation of sensory input into behavioral choice - declines with healthy aging, leading to slower responses, altered accuracy, and negative impacts on quality of life. Recent advances in model-based cognitive neuroscience, particularly drift-diffusion models (DDMs), allow decomposition of PDM into latent components (e.g., evidence accumulation, decision caution, non-decision time) and enable identification of neural circuits associated with each component. This decomposition provides a foundation for targeted neuromodulatory interventions (e.g., transcranial magnetic stimulation) aimed at mitigating age-related cognitive decline. Although a substantial body of literature has successfully combined DDM with neuromodulation to enhance distinct PDM components in young adults, evidence in older populations remains critically limited. Due to age-related morphological, physiological, and connectivity changes, findings from young adults cannot be directly generalized to older adults. This review highlights this research gap and calls for systematic investigation at the intersection of cognitive modeling and neuromodulation to selectively improve distinct components of perceptual decision-making in aging.
