In January 2020, Key Laboratory of Applied Brain and Cognitive Sciences, School of Business and Management (SBM), Shanghai International Studies University (SISU), published an academic paper in the CAS Q1 journal NeuroImage, titled Test-retest reliability of brain responses to risk-taking during the balloon analogue risk task. Prof. Yu Pan is the co-first author and Prof. Hengyi Rao is the corresponding author of this paper. https://doi.org/10.1016/j.neuroimage.2019.116495
The research team is the first to investigate the test-retest reliability of brain activity during The Balloon Analogue Risk Task (BART). They used functional magnetic resonance imaging (fMRI) and evaluated the test-retest reliability of brain responses during a modified (BART) by calculating the intraclass correlation coefficients (ICC) and Dice’s similarity coefficients (DSC). They found that risk processing during the BART was associated with robust activation (median ICC> 0.6) in the mesolimbic-frontal reward system, including the thalamus/midbrain, ventral and dorsal striatum, anterior insula, dorsal lateral prefrontal cortex (DLPFC). The Balloon Analogue Risk Task (BART) provides a reliable and ecologically valid model for the assessment of individual risk-taking propensity and is frequently used in neuroimaging and developmental research. Although the test-retest reliability of risk-taking behavior during the BART is well established, the reliability of brain activation patterns in response to risk-taking during the BART remains elusive. These findings have important implications for future utility of the BART in fMRI to examine brain responses to risk-taking and decision-making.
