ABSTRACT Children born extremely preterm (EP) (<27 weeks gestational age (GA)) are atincreased risk of having a languagedisorder or late language emergence 1-5. The proposed study seeks to identify the neural circuit mechanisms and socio-demographic factors that contribute to variable language outcome in extremely preterm (EP) children at 3 years corrected age (CA). This supplemental funding application is submitted as one of a pair of applications from the University of Pennsylvania/Children's Hospital of Philadelphia (Penn/CHOP) and Cincinnati Children's Hospital Medical Center (CCHMC). The PIs at Penn/CHOP and CCHMC, Drs. DeMauro and Merhar, are PIs of the NICHD Neonatal Research Network (NRN) Clinical Centers at their respective institutions, which serve as the parent studies for the current proposal. The NRN follows all infants born EP and other high-risk infants from birth to 22-26 months CA, collecting developmental outcomes and therapies received, and perinatal, medical, and socio-demographic data. For the proposed project, they engaged highly motivated and qualified junior faculty with expertise in neural imaging and language development from both sites (Dr. Chen from CHOP; Dr. Barnes-Davis from CCHMC). The proposed study employs a suite of magnetoencephalography (MEG) neural measures and language assessments to evaluate if task-based neural measures are differentially associated with variable receptive and expressive language outcome in EP children at 3 years CA in comparison to term-born controls (TC) children. Using tasks developed by Dr. Chen and Dr. Barnes-Davis, neural measures of interest are: (1) auditory encoding processes = M50 latency 6-15, (2) functional connectivity during receptive (story listening) and expressive (verb generation) language processes = weighted phase lag index (wPLI) 16, 17, and (3) resting-state (RS) peak alpha frequency (PAF), a brain rhythm associated with connectivity between neural networks 18-20. Leveraging both the existing CHOP NRN cohort with neonatal and completed developmental data at age 2 years and a CHOP longitudinal TC cohort who have completed longitudinal neuroimaging and developmental data from birth to age 2, MEG and language measures will be obtained in 60 EP and 60 TC children at 3-3.5 years CA. The same MEG task data and language outcome measures will be obtained in the EP and TC cohorts at CCHMC, for a total enrollment of 100 EP and 100 TC participants across two sites, enhancing the power and generalizability of the proposed study. Sharing of methods and data across the two centers permits rapid and efficient data collection of a socioeconomically diverse EP sample. It is anticipated that the elucidation of neural risk factors will provide increased specificity to the nature of variable language outcome in young children born EP. Study findings are also expected to lead to timely and more tailored clinical interventions that shape the maturation of language neural networks and specifically meet the goal of the TALK NOSI, “to engage in activities that will help to elucidate the unique trajectories and needs of late talking children.”

摘要 极早产(EP)(&lt；27周胎龄(GA))的儿童有更高的风险 语言障碍或语言出现迟缓1-5人。这项拟议的研究试图确定神经回路 导致极端不同语言结果的机制和社会人口因素 3岁矫正年龄(CA)的早产(EP)儿童。本补充拨款申请按以下方式提交 宾夕法尼亚大学/费城儿童医院的两份申请之一 (宾夕法尼亚/CHOP)和辛辛那提儿童医院医疗中心(CCHMC)。宾夕法尼亚大学的私人投资经理/印章和 CCHMC，DeMauro博士和Merhar博士，是NICHD新生儿研究网络(NRN)临床中心的PI 在各自的机构，这些机构作为当前提案的家长研究。NRN遵循所有 出生为EP的婴儿和其他高危婴儿从出生到22-26个月的CA，收集发育结果 和接受的治疗，以及围产期、医学和社会人口数据。对于拟议的项目，他们 聘用具有高度积极性和合格的初级教员，具备神经成像和语言方面的专业知识 两个网站的发展(CHOP的陈博士；CCHMC的巴恩斯-戴维斯博士)。建议进行的研究 使用一套脑磁图(MEG)神经测量和语言评估来评估 如果基于任务的神经测量与可变的接受性和表现性语言不同地关联 与足月出生对照(TC)儿童相比，EP儿童在CA 3岁时的结局。使用任务 由Chen博士和Barnes-Davis博士开发的感兴趣的神经测量方法是：(1)听觉编码 流程=M50延迟6-15，(2)接受性(故事倾听)和表现性(动词)过程中的功能连接 生成)语言过程=加权相位滞后指数(WPLI)16、17，以及(3)休眠状态(RS)峰值α 频率(PAF)，与神经网络18-20之间的连通性相关的大脑节律。充分利用两者 现有CHOP NRN队列中有新生儿和2岁时的完整发育数据，且有CHOP 完成纵向神经影像和发育数据的纵向TC队列 在3-3.5岁的CA中，将对60名EP和60名TC儿童进行2岁、MEG和语言测试。这个 将在CCHMC的EP和TC队列中获得相同的MEG任务数据和语言结果衡量标准， 两个站点的100名EP和100名TC参与者的注册总数，增强了 拟议研究的概括性。两个中心之间的方法和数据共享允许快速和 有效收集不同社会经济类型的环保样本数据。据预计，对 神经风险因素将为青少年语言结果变量的性质提供更高的特异性 出生时患有EP的儿童。研究结果也有望导致及时和更有针对性的临床干预 塑造语言神经网络的成熟，特别是满足谈话鼻音的目标， 参与有助于阐明说话迟缓儿童的独特轨迹和需求的活动。
