ABSTRACT Prenatal cocaine exposure (PCE) has ramifications for feedback processing. Measuring neural oscillatory dynamics (during electroencephalography) provides insight into the time signatures and neural processes of feedback processing in adolescents with PCE. We measured spectral power in alpha and theta frequency bands while 49 adolescents with PCE and 34 non-drug exposed (NDE) performed a task with win/no-win feedback. Compared to NDE individuals, those with PCE showed reduced alpha power and increased theta power in response to no-win feedback. These findings suggest altered reactivity in PCE adolescents.

产前接触可卡因的青少年反馈处理的振荡动力学


摘要 产前可卡因暴露 (PCE) 对反馈处理有影响。测量神经振荡动力学（脑电图期间）可以深入了解患有 PCE 的青少年反馈处理的时间特征和神经过程。我们测量了 α 和 θ 频段的光谱功率，同时 49 名患有 PCE 的青少年和 34 名未接触药物 (NDE) 的青少年执行了一项带有赢/不赢反馈的任务。与 NDE 个体相比，PCE 个体在应对无赢反馈时表现出 α 功率降低和 θ 功率增加。这些发现表明 PCE 青少年的反应性发生了变化。
