摘要

Purpose of review

Impulsivity is a risk factor for problematic substance use. Understanding its neural underpinnings requires large neuroimaging samples, which are difficult and costly to obtain. This scoping review aimed to identify open-access datasets that allow researchers to investigate the neural basis of impulsivity in relation to substance use.

Recent Findings

We searched PubMed, Scopus, and major data repositories. 35 openly available datasets with over 200 participants (ranging from 200 to 500,000) were identified that contain (1) impulsivity, (2) substance use, and (3) neuroimaging measures. We compiled this information into a searchable, interactive Shiny-based application to help researchers identify relevant datasets.

Summary

Although access to large datasets is improving, more progress is needed to ensure data are findable, accessible, interoperable, and reusable. This review lowers barriers to using open-access data by guiding researchers toward available datasets relevant to the neural basis of impulsivity and substance use, as well as provides recommendations for future data sharing.
