Abstract

We studied risky decision making (RDM) in 8 healthy adolescents (TC) and 11 adolescents with mild to moderate traumatic brain injuries (TBI) using the Balloon Analog Risk Task (BART) and functional magnetic resonance imaging (fMRI). Participants inflated simulated balloons (with more points awarded to bigger balloons), which might burst at any time. Increasing brain activation levels were associated with increasing balloon size in a largely bilateral network, including cerebellar, inferior parietal, limbic, and frontal areas. Both groups performed similarly and activated similar networks.

摘要

我们使用气球模拟风险任务(BART)和功能磁共振成像(fMRI),对8名健康青少年(TC)和11名轻度至中度创伤性脑损伤(TBI)青少年的风险决策(RDM)进行了研究。参与者给模拟气球充气(气球越大得分越高),气球可能在任何时候爆裂。在一个主要为双侧的网络中,包括小脑、顶下叶、边缘系统和额叶区域,大脑激活水平的增加与气球大小的增加相关。两组表现相似且激活了相似的网络。
