Adolescence is a period of profound biopsychosocial development, with pubertally-driven neural reorganization as social demands increase in peer contexts. The explosive increase in social media access has fundamentally changed peer interactions among youth, creating an urgent need to understand its impact on neurobiological development and mental health. Extant literature indicates that using social media promotes social comparison and feedback seeking (SCFS) behaviors in youth, which portend increased risk for mental health disorders, but little is known about its impact on neurobiological development. We assessed social media behaviors, mental health symptoms, and spontaneous cortical activity using magnetoencephalography (MEG) in 80 typically developing youth (8–16 years) and tested how self-reported pubertal stage moderates their relationship. More mature adolescents who engaged in more SCFS showed weaker fusiform/parahippocampal alpha and medial prefrontal beta activity, and increased symptoms of anxiety and attention problems. Engaging in SCFS on social media during adolescence may thus relate to developmental differences in brain regions that undergo considerable development during puberty. These results are consistent with works indicating altered neurodevelopmental trajectories within association cortices surrounding the onset of many mental health disorders. Importantly, later pubertal stages may be most sensitive to the detrimental effects of social media use.

Dopaminergic projections from the ventral tegmental area (VTA) to limbic regions play a key role in the initiation and maintenance of substance use; however, the relationship between mesolimbic resting-state functional connectivity (RSFC) and alcohol use during development remains unclear. We examined the associations between alcohol use and VTA RSFC to subcortical structures in 796 participants (12–21 years old at baseline, 51 % female) across 9 waves of longitudinal data from the National Consortium on Alcohol and Neurodevelopment in Adolescence. Linear mixed effects models included interactions between age, sex, and alcohol use, and best fitting models were selected using log-likelihood ratio tests. Results demonstrated a positive association between alcohol use and VTA RSFC to the nucleus accumbens. Age was associated with VTA RSFC to the amygdala and hippocampus, and an age-by-alcohol use interaction on VTA-globus pallidus connectivity was driven by a positive association between alcohol and VTA-globus pallidus RSFC in adolescence, but not adulthood. On average, male participants exhibited greater VTA RSFC to the amygdala, nucleus accumbens, caudate, hippocampus, globus pallidus, and thalamus. Differences in VTA RSFC related to age, sex, and alcohol, may inform our understanding of neurobiological risk and resilience for alcohol use and other psychiatric disorders
从腹侧被盖区(VTA)到边缘区域的多巴胺能投射在药物使用的开始和维持过程中起着关键作用;然而,在发育过程中,中边缘静息态功能连接(RSFC)与酒精使用之间的关系仍不清楚。我们研究了国家青少年酒精和神经发育联合会(National Consortium on Alcohol and Neurodevelopment in Adolescence)9波纵向数据中796名参与者(基线年龄为12-21岁,51%为女性)的酒精使用和VTA RSFC与皮层下结构之间的关系。线性混合效应模型包括年龄、性别和饮酒情况之间的交互作用,并通过对数似然比检验选择最佳拟合模型。结果表明,饮酒与通向伏隔核的 VTA RSFC 呈正相关。年龄与通往杏仁核和海马的VTA RSFC相关,年龄与饮酒对VTA-球丛苍白球连通性的交互作用是由青春期饮酒与VTA-球丛苍白球RSFC之间的正相关而非成年期饮酒所驱动的。平均而言,男性参与者的杏仁核、伏隔核、尾状核、海马、球状苍白球和丘脑的VTA RSFC更大。与年龄、性别和酒精有关的VTA RSFC差异可能有助于我们了解酗酒和其他精神疾病的神经生物学风险和恢复能力。

The HEALthy Brain and Child Development (HBCD) Study, a multi-site prospective longitudinal cohort study, will examine human brain, cognitive, behavioral, social, and emotional development beginning prenatally and planned through early childhood. Central to its mission of reducing health disparities is the establishment of the Spanish Language and Culture Committee (SLCC) within the HBCD framework, a significant step towards demographic representation and inclusivity in research. By addressing linguistic and sociocultural barriers and embracing the diverse identities of Hispanic/Latine individuals nationwide, the SLCC aims to promote inclusion, equity, and representation of all Hispanic/Latine subgroups, a population that has been historically misrepresented in health research. In this paper we describe the role of the SLCC in advocating for Hispanic/Latine families within the study, ensuring their inclusion from inception. This report also provides an overview of the SLCC organization, workflow, challenges and lessons learned thus far to reduce stigma and improve study outcomes, highlighting recruitment and retention strategies for the Hispanic/Latine population, and expanding outreach to promote inclusion across diverse Hispanic/Latine subgroups in the United States.
HEALthy Brain and Child Development (HBCD) 研究是一项多站点前瞻性纵向队列研究,将从产前开始并计划到幼儿期对人脑、认知、行为、社会和情感发育进行研究。在 HBCD 框架内成立西班牙语和文化委员会(SLCC)是该研究减少健康差异的核心任务,这是在研究的人口代表性和包容性方面迈出的重要一步。通过解决语言和社会文化障碍以及接纳全国西班牙裔/拉丁裔个人的不同身份,西班牙语言和文化委员会旨在促进所有西班牙裔/拉丁裔亚群体的包容性、公平性和代表性,而这一群体在健康研究中历来代表性不足。在本文中,我们介绍了 SLCC 在研究中为西班牙裔/拉丁裔家庭进行宣传,确保从一开始就将他们纳入研究中的作用。本报告还概述了 SLCC 的组织结构、工作流程、挑战以及迄今为止为减少耻辱感和改善研究结果所吸取的经验教训,重点介绍了针对西班牙裔/拉丁裔人口的招募和保留策略,并扩大了外联范围,以促进美国不同的西班牙裔/拉丁裔亚群体的融入。

Parental mental health is associated with children’s emotion regulation (ER) and risk for psychopathology. The relationship between parental psychopathology and children’s functional ER networks and whether connectivity patterns mediate the relationship between parent and youth psychopathology remains unexplored. Using resting-state functional magnetic resonance imaging data from the Adolescent Brain Cognitive Development Study (N = 4202, mean age = 10.0) and a multilevel approach, we analyzed the relationship between self-reported parental psychopathology and their offsprings’ connectivity of four ER networks, as well as associations with self-reported youth psychopathology at a 3-year follow-up. Parental internalizing and total problems were associated with 1) higher connectivity between a subcortical-cortical integrative and ventrolateral prefrontal cortical (PFC) network, 2) lower connectivity between dorsolateral and ventrolateral PFC networks involved in cognitive aspects of ER, and 3) lower connectivity within a subcortical ER network (β = −0.05–0.04). Parental externalizing and total problems were associated with lower connectivity within the integrative network (βext = −0.05; βtot = −0.04). Mediation analyses yielded direct effects of parental to youth psychopathology, but no mediation effect of ER network connectivity. Overall, our results show that ER network connectivity in youth is related to parental psychopathology, yet do not explain intergenerational transmission of psychopathology.
父母的心理健康与子女的情绪调节(ER)和精神病理学风险有关。父母的精神病理学与儿童的ER功能网络之间的关系,以及连接模式是否会介导父母与青少年精神病理学之间的关系,这些问题仍有待研究。利用青少年大脑认知发展研究(N = 4202,平均年龄 = 10.0)的静息态功能磁共振成像数据和多层次方法,我们分析了自我报告的父母心理病理学与子女的四个ER网络连通性之间的关系,以及在3年随访中与自我报告的青少年心理病理学之间的关联。父母的内化和总体问题与以下因素有关:1)皮层下-皮层整合网络和前额叶皮层(PFC)腹外侧网络之间的连接性较高;2)涉及ER认知方面的前额叶皮层背外侧和腹外侧网络之间的连接性较低;3)皮层下ER网络内部的连接性较低(β = -0.05-0.04)。父母的外化问题和总体问题与整合网络内较低的连通性有关(βext = -0.05;βtot = -0.04)。中介分析得出了父母对青少年心理病理学的直接影响,但ER网络连通性没有中介效应。总之,我们的研究结果表明,青少年的ER网络连通性与父母的精神病理学有关,但并不能解释精神病理学的代际传递。

Combining existing datasets to investigate key questions in developmental cognitive neuroscience brings exciting opportunities and unique challenges. However, many data pooling methods require identical or harmonized methodologies that are often not feasible. We propose Integrative Data Analysis (IDA) as a promising framework to advance developmental cognitive neuroscience with secondary data analysis. IDA serves to test hypotheses by combining data of the same construct from commensurate (but not identical) measures. To overcome idiosyncrasies of neuroimaging data, IDA explicitly evaluates if measures across studies assess the same construct. Moreover, IDA allows investigators to examine meaningful individual variability by de-confounding source-specific differences. To demonstrate IDA’s potential, we explain foundational concepts, outline necessary steps, and apply IDA to volumetric measures of hippocampal subfields from 443 4- to 17-year-olds across three independent studies. We identified commensurate measures of Cornu Ammonis (CA) 1, dentate gyrus (DG)/CA3, and Subiculum (Sub). Model testing supported use of IDA to create IDA factor scores. We found age-related differences in DG/CA3, not but CA1 and Sub volume in the integrated dataset. By successfully demonstrating IDA, our hope is that future innovations come from the combination of existing neuroimaging data to create representative integrated samples when testing critical developmental questions.
结合现有数据集来研究发育认知神经科学中的关键问题,既带来了令人兴奋的机遇,也带来了独特的挑战。然而,许多数据汇集方法需要相同或统一的方法,而这往往是不可行的。我们提出了整合数据分析(IDA)这一前景广阔的框架,通过二次数据分析来推动发育认知神经科学的发展。整合数据分析(IDA)的作用是通过合并来自相称(但不完全相同)测量方法的相同构造的数据来检验假设。为了克服神经影像数据的特殊性,IDA 明确评估了不同研究的测量数据是否评估了相同的构象。此外,IDA 还允许研究人员通过消除来源特异性差异来检查有意义的个体变异性。为了证明 IDA 的潜力,我们解释了基本概念,概述了必要步骤,并将 IDA 应用于三项独立研究中 443 名 4 至 17 岁儿童的海马亚区容积测量。我们确定了 Cornu Ammonis (CA) 1、齿状回 (DG)/CA3 和 Subiculum (Sub) 的相应测量值。模型测试支持使用 IDA 创建 IDA 因子分数。我们在综合数据集中发现了与年龄有关的 DG/CA3 差异,而不是 CA1 和 Sub 体积的差异。通过成功展示 IDA,我们希望未来的创新能够来自于现有神经影像数据的结合,从而在测试关键发育问题时创建具有代表性的综合样本。

Puberty and associated changes in pubertal hormones influence structural brain development. Hormones such as dehydroepiandrosterone (DHEA) and progesterone remain understudied, and it remains unclear how these aspects of puberty contribute uniquely to structural brain development. We used the Human Connectome Project in Development cross-sectional sample of 1304 youth (aged 5–21 years) to investigate unique contributions of sex, age, pubertal stage, DHEA, testosterone, estradiol, and progesterone to cortical thickness, surface area, and subcortical volume development within functionally-relevant networks. Sex and age explain the most unique variance in all three aspects of structural development. Pubertal stage and pubertal hormones uniquely contribute more to cortical surface area, compared to thickness. Among the pubertal hormones, progesterone contributed unique variance to surface area in the default mode network, as well as to thickness in the orbito-affective network. Pubertal mechanisms also contributed unique variance to subcortical volumes. This demonstrates unique relations of understudied pubertal hormones to brain structure development and may help understand risk for psychopathology.
青春期和青春期激素的相关变化会影响大脑结构的发育。对脱氢表雄酮(DHEA)和孕酮等激素的研究仍然不足,目前仍不清楚这些青春期激素对大脑结构发育的独特作用。我们利用人类发育连接组项目(Human Connectome Project in Development)对 1304 名青少年(5-21 岁)的横断面样本进行了研究,调查了性别、年龄、青春期阶段、DHEA、睾酮、雌二醇和孕酮对功能相关网络中皮层厚度、表面积和皮层下体积发育的独特贡献。在结构发育的所有三个方面,性别和年龄解释了最独特的差异。与厚度相比,青春期阶段和青春期激素对皮质表面积的独特贡献更大。在青春期荷尔蒙中,孕酮对默认模式网络的表面积和轨道-情感网络的厚度有独特的影响。青春期机制对皮层下体积也有独特的影响。这显示了未被充分研究的青春期激素与大脑结构发育的独特关系,可能有助于了解精神病理学的风险。

Enhancing the generalizability of neuroimaging studies requires actively engaging participants from under-represented communities. This paper leverages qualitative data to outline participant-driven recommendations for incorporating under-represented populations in neuroimaging protocols. Thirty-one participants, who had participated in neuroimaging research or could be eligible for one as part of an ongoing longitudinal study, engaged in semi-structured one-on-one interviews (84 % under-represented ethnic-racial identities and low-income backgrounds). Through thematic analysis, we identified nine relevant research practices from participants' reports, highlighting aspects of their experience that they appreciated and suggestions for improvement: (1) forming a diverse research team comprising members with whom participants can interact as equals; (2) increasing accessibility to research by providing transportation and flexible scheduling; (3) providing family-oriented spaces; (4) enriching the campus visits to include optional on-campus activities to connect with the University; (5) developing safe strategies to accommodate participants with tattoos during the MRI; (6) incorporating engaging and interactive tasks during neuroimaging sessions; (7) providing small gifts, such as a picture of one’s brain, in addition to financial compensation; (8) sharing research findings with the research participants; and (9) fostering long-term bidirectional relationships. The findings may be used to develop best practices for enhancing participant diversity in future neuroimaging studies.
要提高神经成像研究的可推广性,就必须积极吸引代表性不足群体的参与者参与。本文利用定性数据概述了以参与者为导向的建议,以便将代表性不足的人群纳入神经成像方案。31 名曾参与神经成像研究或有资格参与正在进行的纵向研究的参与者参与了半结构化一对一访谈(84% 的参与者具有代表性不足的种族身份和低收入背景)。通过主题分析,我们从参与者的报告中确定了九项相关的研究实践,强调了他们所赞赏的经验和改进建议:(1) 组建一个由参与者可以平等交流的成员组成的多元化研究团队;(2) 通过提供交通和灵活的时间安排,提高研究的可及性;(3) 提供面向家庭的空间;(4) 丰富校园参观活动,包括可选的校内活动,与大学建立联系;(5) 制定安全策略,在核磁共振成像过程中照顾有纹身的参与者;(6) 在神经成像过程中加入吸引人的互动任务;(7) 除经济补偿外,提供小礼物,如个人大脑的照片;(8) 与研究参与者分享研究成果;以及 (9) 培养长期的双向关系。研究结果可用于在未来的神经成像研究中制定提高参与者多样性的最佳实践。

Although prior studies have revealed alterations in gray matter volume (GMV) among individuals with internet gaming disorder (IGD). The brain's multifaceted functions hinge crucially on the intricate connections and communication among distinct regions. However, the intricate interaction of information between brain regions with altered GMV and other regions, and how they synchronize with various neurotransmitter systems, remains enigmatic. Therefore, we aimed to integrate structural, functional and molecular data to explore the GMV-based Granger causal connectivity abnormalities and their correlated neurotransmitter systems in IGD adolescents. Voxel-based morphometry (VBM) analysis was firstly performed to investigate GMV differences between 37 IGD adolescents and 35 matched controls. Brain regions with altered GMV were selected as seeds for further Granger causality analysis (GCA). Two-sample t tests were performed using the SPM12 toolkit to compare the GMV and Granger causal connectivity between IGD and control groups (GRF corrected, Pvoxel<0.005, Pcluster<0.05). Then, GMV-based Granger causal connectivity was spatially correlated with PET- and SPECT-derived maps covering multifarious neurotransmitter systems. Multiple comparison correction was performed using false discovery rate (FDR). Compared with controls, IGD adolescents showed higher GMV in the caudate nucleus and lingual gyrus. For the GCA, IGD adolescents showed higher Granger causal connectivity from insula, putamen, supplementary motor area (SMA) and middle cingulum cortex (MCC) to the caudate nucleus, and lower Granger causal connectivity from superior/inferior parietal gyrus (SPG/IPG) and middle occipital gyrus (MOG) to the lingual gyrus. Besides, GMV-based Granger causal connectivity of IGD adolescents were associated with the dopaminergic, serotonergic, GABAergic and noradrenaline systems. This study revealed that the caudate nucleus and lingual gyrus may be the key sites of neuroanatomical changes in IGD adolescents, and whole-brain Granger causal connectivity abnormalities based on altered GMV involved large brain networks including reward, cognitive control, and visual attention networks, and these abnormalities are associated with a variety of neurotransmitter systems, which may be associated with higher reward sensitivity, cognitive control, and attention control dysfunction.
尽管先前的研究显示,网络游戏障碍(IGD)患者的灰质体积(GMV)发生了改变。大脑的多方面功能关键取决于不同区域之间错综复杂的联系和交流。然而,GMV改变的大脑区域与其他区域之间错综复杂的信息互动,以及它们如何与各种神经递质系统同步,仍然是个谜。因此,我们旨在整合结构、功能和分子数据,探索 IGD 青少年基于 GMV 的格兰杰因果连接异常及其相关神经递质系统。首先进行体素形态计量(VBM)分析,研究37名IGD青少年与35名匹配对照组之间的GMV差异。选取 GMV 发生变化的脑区作为种子区域,进一步进行格兰杰因果关系分析(GCA)。使用 SPM12 工具包进行双样本 t 检验,比较 IGD 组和对照组之间的 GMV 和格兰杰因果连通性(GRF 校正,Pvoxel<0.005,Pcluster<0.05)。然后,将基于 GMV 的格兰杰因果连通性与正电子发射计算机断层显像(PET)和正电子发射计算机断层显像(SPECT)得出的涵盖多种神经递质系统的图谱进行空间关联。使用错误发现率(FDR)进行多重比较校正。与对照组相比,IGD 青少年尾状核和舌回的 GMV 更高。在GCA方面,IGD青少年从岛叶、普塔门、辅助运动区(SMA)和中腔皮层(MCC)到尾状核的格兰杰因果连接性较高,而从顶上/顶下回(SPG/IPG)和枕中回(MOG)到舌回的格兰杰因果连接性较低。此外,IGD青少年基于GMV的格兰杰因果连通性与多巴胺能、血清素能、GABA能和去甲肾上腺素系统有关。该研究揭示,尾状核和舌回可能是IGD青少年神经解剖学变化的关键部位,基于GMV改变的全脑格兰杰因果连接异常涉及包括奖赏、认知控制和视觉注意力网络在内的大型脑网络,这些异常与多种神经递质系统有关,可能与奖赏敏感性增高、认知控制和注意力控制功能障碍有关。

Impulsivity and cognitive function are essential for understanding behavioral regulation, particularly in relation to health-risk behaviors like substance use, physical activity, and academic performance. This study examined the factor structure underlying executive function in adolescents using the UPPS-P Impulsive Behavior Scale and NIH Toolbox Cognition Battery. We explored how parental monitoring moderates, and peer network health and perceived stress mediate, relationships between cognitive function and outcomes such as BMI, physical activity, and academic performance. Exploratory factor analysis (EFA) on 2228 observations identified a four-factor model (BIC = −97.92, RMSEA = 0.040, TLI = 0.936), validated by confirmatory factor analysis (CFA) (CFI = 0.961, RMSEA = 0.055). Structural equation modeling (SEM) on 5902 observations showed that parental monitoring moderated Factor 1 (adaptive impulsivity) in relation to physical activity and academic performance, while peer network health mediated Factor 2 (emotional impulsivity) effects on BMI and physical activity. This model underscores the influence of peer relationships, parental involvement, and stress on cognitive, health, and academic outcomes, suggesting that interventions enhancing peer support, reducing stress, and promoting healthy behaviors may improve adolescent well-being.
冲动性和认知功能对于了解行为调节,尤其是与药物使用、体育锻炼和学习成绩等健康风险行为有关的行为调节至关重要。本研究使用 UPPS-P 冲动行为量表和美国国立卫生研究院工具箱认知测验,对青少年执行功能的基础因子结构进行了研究。我们探讨了认知功能与体重指数、体育锻炼和学习成绩等结果之间的关系,即父母的监督如何调节,以及同伴网络健康和感知压力如何起中介作用。对 2228 个观察结果进行的探索性因子分析(EFA)确定了一个四因子模型(BIC = -97.92,RMSEA = 0.040,TLI = 0.936),并通过确认性因子分析(CFA)进行了验证(CFI = 0.961,RMSEA = 0.055)。对 5902 个观测点进行的结构方程建模(SEM)显示,父母的监督调节了因子 1(适应性冲动)对体育锻炼和学习成绩的影响,而同伴网络健康则调节了因子 2(情绪冲动)对体重指数和体育锻炼的影响。这一模型强调了同伴关系、父母参与和压力对认知、健康和学业成绩的影响,表明加强同伴支持、减少压力和促进健康行为的干预措施可以改善青少年的福祉。

Cognitive computational neuroscience has received broad attention in recent years as an emerging area integrating cognitive science, neuroscience, and artificial intelligence. At the heart of this field, approaches using encoding models allow for explaining brain activity from latent and high-dimensional features, including artificial neural networks. With the notable exception of temporal response function models that are applied to electroencephalography, most prior studies have focused on adult subjects, making it difficult to capture how brain representations change with learning and development. Here, we argue that future developmental cognitive neuroscience studies would benefit from approaches relying on encoding models. We provide an overview of encoding models used in adult functional magnetic resonance imaging research. This research has notably used data with a small number of subjects, but with a large number of samples per subject. Studies using encoding models also generally require task-based neuroimaging data. Though these represent challenges for developmental studies, we argue that these challenges may be overcome by using functional alignment techniques and naturalistic paradigms. These methods would facilitate encoding model analysis in developmental neuroimaging research, which may lead to important theoretical advances.
认知计算神经科学作为融合认知科学、神经科学和人工智能的新兴领域,近年来受到广泛关注。作为这一领域的核心,使用编码模型的方法可以从潜在的高维特征(包括人工神经网络)来解释大脑活动。除了应用于脑电图的时间反应函数模型之外,之前的大多数研究都集中在成年受试者身上,因此很难捕捉到大脑表征是如何随着学习和发育而变化的。在此,我们认为未来的发育认知神经科学研究将受益于依赖编码模型的方法。我们概述了成人功能磁共振成像研究中使用的编码模型。这些研究主要使用少量受试者的数据,但每个受试者都有大量样本。使用编码模型的研究通常还需要基于任务的神经成像数据。虽然这些都是发展研究面临的挑战,但我们认为可以通过使用功能配准技术和自然范式来克服这些挑战。这些方法将促进发育神经影像研究中的编码模型分析,并可能带来重要的理论进展。
