项目摘要

In utero exposure to environmental chemicals can disturb neurobehavioral development in both animals and in humans. The pathways linking in utero environmental exposures to neurobehavioral development likely involve exposure-induced changes in the function of neural circuits that support cognitive control and reward processes. We hypothesize that changes in the function of these circuits may act as a pathway between environmental exposure and a range of maladaptive behaviors that commonly emerge in late childhood and adolescence, a period that has been largely understudied with respect to the effects of prenatal exposures on neurodevelopmental outcomes. Such behavioral symptoms include attention problems, substance abuse, and psychotic experiences. This study will: 1) apply novel pattern recognition approaches to identify specific exposure profiles of complex high-dimensional mixtures of prenatal chemical and social exposures and examine how these profiles explain variation in risk for these behavioral symptoms in adolescence; 2) use task and resting state functional MRI (fMRI) to identify how distinct exposure profiles affect circuits that support cognitive control and reinforcement learning; and 3) explore if exposure-induced changes in brain activation and connectivity mediate associations between prenatal exposure profiles and behavioral symptoms in adolescence. Impact: This R01 will integrate advanced pattern recognition methods, a cognitive neuroscience approach and state-of-the-art fMRI techniques to explore brain pathways through which prenatal exposures alter behavior later in adolescence. We will explore circuit-based changes in brain function that may mediate associations between prenatal exposure profiles and symptoms of psychiatric disorders that typically emerge and co-occur in adolescence. By simultaneously studying mixtures of chemical and social stressors as well as profiles of co- occurring symptoms, we will greatly enhance our ability to comprehensively characterize the complex impacts of prenatal environmental exposures on behavioral symptoms in adolescence. Our findings will allow public health interventions to improve the quality of children's perinatal environment and the development of novel circuit-specific intervention tools.

在子宫内暴露于环境化学物质会扰乱动物和人类的神经行为发育。人类。子宫内环境暴露与神经行为发育的联系途径可能涉及暴露引起的支持认知控制和奖励的神经回路功能的变化流程。我们假设这些电路功能的变化可能充当两者之间的通路环境暴露和一系列通常出现在童年晚期的适应不良行为青春期，这一时期对于产前接触对婴儿的影响尚未得到充分研究。神经发育结果。这些行为症状包括注意力问题、药物滥用和精神病经历。本研究将：1）应用新颖的模式识别方法来识别特定的产前化学和社会暴露的复杂高维混合物的暴露概况研究这些概况如何解释青春期这些行为症状的风险变化； 2）使用任务和静息态功能 MRI (fMRI)，以确定不同的暴露曲线如何影响支持的电路认知控制和强化学习； 3）探索暴露是否会引起大脑激活的变化连通性介导产前暴露状况与行为症状之间的关联青春期。影响：这款 R01 将集成先进的模式识别方法、认知神经科学方法和最先进的功能磁共振成像技术，用于探索产前暴露改变以后行为的大脑通路在青春期。我们将探索大脑功能中基于回路的变化，这些变化可能会介导产前暴露情况和通常出现并同时发生的精神疾病症状青春期。通过同时研究化学和社会压力源的混合物以及共同的概况出现的症状，我们将大大增强综合描述复杂影响的能力产前环境暴露对青春期行为症状的影响。我们的研究结果将使公众改善儿童围产期环境质量的健康干预措施和开发新产品电路特定的干预工具。
