项目摘要

Project Summary This application describes the research plan and program of study leading to a PhD as part of a combined MD- PhD Program at the University of Nebraska Medical Center and the Boys Town National Research Hospital. The central goal of this research plan is to identify how dehydroepiandrosterone (DHEA), testosterone, and estradiol modulate the development of cognitive systems serving selective attention and working memory processing. Briefly, the pubertal transition period is marked by significant increases in these hormones and substantial developmental advancements in higher-order cognitive functions, including working memory, selective attention, and others. However, on the other hand, the incidence of psychiatric disease also increases during puberty, and is accompanied by greater sex differences in disease prevalence. It has been suggested that this emergence of psychiatric illness during puberty might be associated with the drastic hormonal changes that mark this developmental stage, but the net impact of these hormonal changes on brain function and cognition is poorly understood. This F30 fellowship proposal will examine the sex and region-specific effects of DHEA, testosterone, and estradiol on working memory and selective attention processing using an advanced dynamic functional mapping approach based on magnetoencephalography (MEG), and includes a rigorous training and career development plan for a future physician-scientist in the areas of pediatric psychiatry and developmental cognitive neuro- science. The specific aims are (1) to examine the unique effects of pubertal hormones in predicting performance on selective attention and working memory tasks and (2) to identify the relationship between sex steroid hormone levels, neural oscillatory dynamics, and behavior during attention and working memory tasks. The trainee is a minority MD/PhD student in his 2nd year of PhD study who has already distinguished himself through two first- authored manuscripts in top journals, participation and presentation in scientific conferences, and a strong history of academic achievement. In sum, this application for an F30 fellowship will use MEG, advanced source reconstruction methods, neural oscillatory analyses, and hair-sampled hormone analysis to delineate the relationship between pubertal hormone levels, brain dynamics, and cognitive development. The program of study is designed to support this research plan through rigorous training by an internationally known expert in MEG and dynamic brain mapping who has a strong record of mentoring trainees, as well as an expert collaborator in pubertal hormone analysis and interpretation, with the primary goals of developing and expanding the research and clinical skills of the applicant to produce a physician-scientist who is well equipped and prepared for the next stage of his career.
项目摘要 本申请描述了研究计划和研究计划,导致博士学位的一部分,结合MD- 博士课程在内布拉斯加大学医学中心和男孩镇国家研究医院。的 这项研究计划的中心目标是确定脱氢表雄酮(DHEA),睾酮和雌二醇 调节服务于选择性注意和工作记忆处理的认知系统的发展。 简而言之,青春期过渡期的特点是这些激素显着增加, 高级认知功能的发展进步,包括工作记忆,选择性注意, 等人然而,另一方面,精神疾病的发病率在青春期也会增加, 伴随着疾病流行率的性别差异更大。有人认为,这种出现 青春期的精神疾病可能与标志着这一点的激素剧烈变化有关。 发育阶段,但这些激素变化对大脑功能和认知的净影响很差 明白 这个F30奖学金提案将检查DHEA,睾酮和 雌二醇对工作记忆和选择性注意加工的影响 方法基于脑磁图(MEG),包括严格的培训和职业发展 计划在儿科精神病学和发展认知神经领域的未来医生,科学家, 科学具体目的是:(1)研究青春期激素在预测成绩方面的独特作用 (2)确定性类固醇激素与选择性注意和工作记忆任务的关系 水平,神经振荡动力学,以及注意力和工作记忆任务期间的行为。学员是一名 少数民族医学博士/博士生在他的第二年博士研究谁已经通过两个第一突出自己- 在顶级期刊上撰写手稿,参与科学会议并发表演讲,以及强大的历史 学术成就。总之,F30奖学金的申请将使用MEG,高级源 重建方法,神经振荡分析,和头发采样激素分析,以描绘 青春期激素水平、大脑动力学和认知发育之间的关系。学习计划 旨在通过由国际知名的MEG专家进行严格的培训来支持这项研究计划 和动态大脑图谱,他在指导受训者方面有很好的记录, 青春期激素分析和解释,主要目标是发展和扩大研究 申请人的临床技能,以产生一个医生,科学家谁是装备精良,并为下一个准备 他职业生涯的阶段。
