项目摘要
Abstract
Understanding neurodevelopmental and early onset origins of mental disorders is essential to improve the
quality of life for children and adolescents and their families, and to reduce societal burden through early
identification and intervention. My long-term career goal is to become a fully funded, independent investigator
to study the role of biological sex and hormones in emotional neurodevelopment and risk for childhood and
adolescent onset of affective disorders. Fetal hormones may have permanent organizational effects that lay
the foundation for, and may even limit, subsequent organizational and activational effects of sex hormones on
brain circuits during puberty. Thus, the interaction of both fetal and pubertal hormone exposure may contribute
to individual and sex-based differences in risk for affective disorders. Although I have extensive research
experience studying typical neurodevelopment using magnetic resonance imaging (MRI) methods, the present
application will provide me with multidisciplinary training and mentorship in assessing emotional processing
and mental health in children and adolescents, as well as recruiting and collecting imaging data in pediatric
clinical samples. The specific research aims of this proposal allow for development of these skillsets by
investigating how increased fetal testosterone levels impact emotional processing and its neural substrates,
including the amygdala and its connectivity with the prefrontal cortex, in children. To accomplish this goal, I will
address these pressing questions by studying patients with a clinical condition that leads to high fetal
testosterone exposure, known as classical Congenital Adrenal Hyperplasia (CAH). Utilizing emotional
behavioral tasks both inside and outside the scanner, recording tonic and phasic heart rate and skin
conductance activity, and implementing multi-modal magnetic resonance imaging (MRI), I will investigate
emotional processing, as well as amygdala and prefrontal structure and connectivity in 40 CAH children (ages
8 to 12 years, 50% girls) and 40 controls matched for age, sex, and early pubertal maturity. By determining
how fetal testosterone influences emotional neurodevelopment in late childhood in the current study, future
research will focus on longitudinally following these youth to investigate how hormonal changes during mid-to-
late puberty may interact with fetal hormonal programming to confer risk for affective disorders. Long-term
goals of the proposal are to enhance and refine my training in child and adolescent psychiatry, affective
neuroscience, pediatric clinical neuroimaging, and endocrinology. Ultimately, the opportunity of a mentored
career development award will be a critical next step to building a productive developmental neuroimaging
laboratory dedicated to improving our understanding of, and creating better prevention programs for, individual
and sex differences in the risk for affective disorders that begin to emerge during childhood and adolescence.

了解神经发育和早期发作的精神障碍起源对于改善
儿童和青少年及其家人的生活质量,并通过早期减轻社会负担
识别和干预。我的长期职业目标是成为一名全面资助的独立调查员
研究生物性和激素在情绪神经发育中的作用以及儿童时期的风险
情感障碍的青少年发作。胎儿激素可能具有永久的组织影响
性激素的基础,甚至可能限制随后的组织和激活影响
青春期期间的脑电路。因此,胎儿和青春期激素暴露的相互作用可能有助于
在情感障碍风险上的个人和基于性别的差异。尽管我有广泛的研究
使用磁共振成像(MRI)方法研究典型神经发育的经验,目前
应用将为我提供评估情绪处理的多学科培训和指导
以及儿童和青少年的心理健康,以及小儿招募和收集成像数据
临床样品。该提案的具体研究目的允许通过
调查胎儿睾丸激素水平升高如何影响情绪处理及其神经底物,
包括杏仁核及其与前额叶皮层的连通性在儿童中。为了实现这一目标,我将
通过研究具有临床状况的患者来解决这些紧迫的问题,导致胎儿高
睾丸激素暴露,称为经典先天性肾上腺增生(CAH)。利用情感
扫描仪内部和外部的行为任务,记录滋补和阶段性心率和皮肤
电导活性并实施多模式磁共振成像(MRI),我将研究
情绪处理,以及40 CAH儿童的杏仁核和前额叶结构和连通性(年龄
8至12岁,50%的女孩)和40个对照的年龄,性别和青春期早期成熟。通过确定
胎儿睾丸激素如何在当前研究的童年后期影响情绪神经发育
研究将侧重于这些年轻人纵向研究,以调查荷尔蒙如何在中午到中期变化
青春期晚期可能与胎儿荷尔蒙编程相互作用,以赋予情感障碍的风险。长期
该提案的目标是增强和完善我在儿童和青少年精神病学上的培训
神经科学,小儿临床神经影像学和内分泌学。最终,一个导师的机会
职业发展奖将是建立富有成效的发展神经影像学的关键下一步
实验室致力于提高我们对个人的理解并为个人创建更好的预防计划
以及在童年和青春期开始出现的情感障碍风险的性别差异。
