DESCRIPTION (provided by applicant): This grant proposes to study both structural and functional correlates of brain developmental maturation and network organization using advanced imaging techniques in our human populations and similar correlates in newborn rodents with a focus on defining basic mechanisms of repair. The grant will encompass three projects and two cores: Project I) repair after ischemic injury in the term newborn - using both structural and metabolic serial imaging to evaluate how the injuries have altered the brain, its response to injury in the perinatal period, and how structural connectivity relates to neurodevelopmental outcome. This cohort will include babies treated with hypothermia. Project II) repair in high risk newborns with congenital heart disease- there is delayed brain development in this high risk population. Using structural and metabolic imaging, we will determine whether this disorder of development is associated with abnormalities in brain connectivity and functional outcome. Project III) repair after early preterm birth - our data show many preterm infants to have abnormalities of cerebellar maturation, abnormalities of white matter development or progressive white matter disease with infection. Using structural and metabolic imaging, we will determine whether altered patterns of connectivity are consistent or variable, whether recovery from these insults is possible and whether connectivity is permanently or transiently disrupted by these early ex-utero life events. There is an administrative Core for data management including biostatistical support, budgetary oversight, training and seminars. The Imaging and Neurobehavior Core (Services Core) will support the three human imaging projects by ensuring standardization of methods and tracking of imaging acquisition at the various testing time points. In addition, this Core will provide Neurobehavioral testing at all of the follow-up visits, and will be responsible for tracking patients for all projets.

描述（由申请人提供）：该赠款建议使用人类种群中的先进成像技术研究大脑发育成熟和网络组织的结构和功能相关性，并在新生啮齿动物中相关的相关性，重点是定义基本修复机制。该赠款将涵盖三个项目和两个核心：项目i）在新生儿一词中缺血性损伤后修复 - 使用结构和代谢串行成像来评估损伤如何改变大脑，其对围产期损伤的反应以及与神经发育结果的结构连通性如何相关。该队列将包括接受体温过低的婴儿。项目II）维修高风险新生儿的先天性心脏病 - 这种高风险人群的大脑发育延迟。使用结构和代谢成像，我们将确定这种发育障碍是否与大脑连通性和功能结果的异常有关。项目iii）早产早期修​​复 - 我们的数据显示，许多早产儿都有小脑成熟，白质发育异常或感染性白质疾病的异常。使用结构和代谢成像，我们将确定连通性的变化模式是一致还是可变，是否可能从这些侮辱中恢复，以及连通性是否会被这些早期的前USTERO生活事件永久或瞬时破坏。数据管理有一个行政核心，包括生物统计支持，预算监督，培训和研讨会。成像和神经行为核心（服务核心）将通过确保方法的标准化和在各种测试时间点跟踪成像采集来支持三个人类成像项目。此外，该核心将提供神经行为 在所有后续访问中进行测试，并将负责跟踪所有Projets的患者。
