Brain responses during delay discounting in youth at high-risk for substance use disorders

Tarah J Butcher, Mario Dzemidzic, Jaroslaw Harezlak, Leslie A Hulvershorn, Brandon G Oberlin
2021 NeuroImage: Clinical  
Offspring of parents with substance use disorders (SUD) discount future rewards at a steeper rate on the monetary delay discounting task (DD) than typically developing youth.  ...  However, brain activation during DD has yet to be studied in drug naïve youth with a family history (FH) of SUD. Here, we investigate brain activation differences in high-risk youth during DD.  ...  During two delay discounting scans (7:25 each) 365 whole-brain blood oxygenation level dependent (BOLD) contrast volumes were acquired using a multiband (MB) echo planar imaging (EPI) sequence (Center  ...
