In this study, CSD topographic analysis yielded three key findings: i) loss condition showed bilateral frontal sources while the gain condition additionally had a prominent midfrontal source; ii) HR offspring (younger males and females as well as older males) displayed weaker CSD sources at the frontal regions in comparison their LR counterparts; and iii) a weaker prefrontal sink activation was found in younger HR offspring compared to the LR group during both loss and gain conditions in males and only during loss condition in females.
