Abstract

Impaired cognitive control is a consequence of cocaine exposure. Difficulty with feedback processing may underlie this impairment. We examined neural correlates of feedback processing using event-related potentials (ERPs) in 49 prenatally cocaine-exposed (PCE) and 34 nondrug exposed (NDE) adolescents. Adolescents performed a reward-feedback task with win/no-win feedback in a chance-based task. We investigated amplitude and latency of the feedback-related negativity (FRN) and P300 ERP components and source-based estimates elicited during feedback processing. PCE adolescents had smaller P300 amplitudes for no-win feedback, and source analysis in the P300 time window revealed differences between groups localized to the dorsal anterior cingulate cortex.

摘要

认知控制受损是可卡因暴露的一个后果。反馈处理困难可能是这种损伤的潜在原因。我们使用事件相关电位(ERP)研究了49名产前暴露于可卡因(PCE)的青少年和34名未接触毒品(NDE)的青少年在反馈处理方面的神经相关性。青少年在一个基于机会的任务中执行带有赢/未赢反馈的奖励反馈任务。我们研究了反馈相关负波(FRN)和P300 ERP成分的幅度和潜伏期,以及在反馈处理过程中引发的基于源的估计。PCE青少年在未赢反馈时的P300幅度较小,并且在P300时间窗口的源分析显示,两组之间的差异定位于背侧前扣带回皮层。
