PROJECT SUMMARY/ABSTRACT Anxiety and mood disorders are the most common psychiatric conditions. They are also highly comorbid, and co-occurrence is associated with worse patient outcomes. Neurobehavioral dysfunction in cognitive control and emotional reactivity are considered fundamental mechanisms of disorder onset and progression. To inform effective preventative treatments, it is critical to identify modifiable factors that directly impact these transdiagnostic processes. Sleep is one such factor. The deepest stage of sleep, slow-wave sleep, is consistently reduced in most psychiatric conditions and can be modified using a variety of techniques. Slow-wave sleep predominates over the prefrontal cortex, providing particular benefit to cognitive processes, including cognitive control. Cognitive control is instrumental in downregulating negative affect to aversive stimuli. The aim of the current study is to elucidate the role of slow-wave sleep in cognitive control and emotional reactivity to aversive stimuli. We will study 40 young adults with elevated anxiety and depression symptoms and sleep disturbance. Participants will complete two overnights in our sleep lab with polysomnography to assess sleep architecture. Participants will also wear an acoustic stimulation device to enhance slow-wave sleep. During one of the overnights, the device will play sub-arousal tones to boost slow-wave sleep; during the other overnight, tone volume will be zero. The day after each overnight, participants will complete assessments of cognitive control and emotional reactivity in an fMRI scanner. We will examine effects of acoustic enhancement of slow-wave sleep on neurobehavioral measures of cognitive control and emotional reactivity and whether improvements in emotional reactivity occur through cognitive control improvements. This study will elucidate sleep-based mechanisms of anxiety and mood disorder onset in an at-risk sample and inform innovative, targeted, accessible sleep preventative treatments. The candidate possesses skills in sleep manipulation, polysomnography, and assessment of cognitive processes to conduct the proposed research. With additional critical training in 1) advanced targeted sleep manipulation and sleep EEG spectral analysis, 2) cognitive-affective neuroscience and fMRI, and 3) clinical knowledge and treatment of anxiety and mood disorders, the Principal Investigator will obtain the skills necessary to develop an independent research program focused on sleep and mental health. Training and research activities for the current proposal will be completed at the University of Pittsburgh School of Medicine. The Department of Psychiatry and the Center for Sleep and Circadian Science are leaders in sleep and mental health research and devoted to the professional development of early career scientists. The candidate has assembled a mentorship team of experienced independent researchers and clinicians with expertise in the proposed research aims and a successful history of mentorship. The intellectual and material resources provided by the University of Pittsburgh, combined with the proposed mentorship team’s guidance strongly position the candidate to achieve her proposed training, research, and career goals.

项目总结/摘要 焦虑和情绪障碍是最常见的精神疾病。它们也是高度共病的， 同时发生与更差的患者结局相关。认知控制中的神经行为功能障碍， 情绪反应被认为是疾病发作和发展的基本机制。通知 有效的预防性治疗，关键是要确定可改变的因素，直接影响这些 transdiagnosis过程睡眠就是这样一个因素。睡眠的最深阶段，慢波睡眠， 在大多数精神疾病中减少，并且可以使用各种技术进行修改。慢波睡眠 在前额叶皮层中占主导地位，为认知过程提供特别的益处，包括认知 控制认知控制是负调节负面情绪厌恶刺激的工具。的目的 本研究旨在阐明慢波睡眠在认知控制和厌恶情绪反应中的作用 刺激。我们将研究40名患有焦虑和抑郁症状以及睡眠障碍的年轻人。 参与者将在我们的睡眠实验室完成两个通宵的多导睡眠图，以评估睡眠结构。 参与者还将佩戴声学刺激设备以增强慢波睡眠。中的一个期间 在夜间，该设备将播放亚唤醒音调以促进慢波睡眠;在另一个夜间， 体积将为零。在每一夜之后的第二天，参与者将完成认知控制的评估， 和情绪反应的功能磁共振成像扫描仪。我们将研究慢波的声学增强效应 睡眠对认知控制和情绪反应的神经行为测量以及 情绪反应通过认知控制的改善而发生。这项研究将阐明基于睡眠的 焦虑和情绪障碍发作的机制在一个有风险的样本，并告知创新，有针对性，可访问 睡眠预防治疗候选人拥有睡眠控制，多导睡眠图， 评估认知过程，以进行拟议的研究。在1）中进行额外的关键培训 先进的有针对性的睡眠操作和睡眠脑电图频谱分析，2）认知情感神经科学和 fMRI和3）焦虑和情绪障碍的临床知识和治疗，主要研究者将 获得必要的技能，以开发一个独立的研究计划，重点是睡眠和心理健康。 本提案的培训和研究活动将在匹兹堡大学学院完成 医学。精神病学系和睡眠与昼夜节律科学中心是睡眠领域的领导者 和心理健康研究，并致力于早期职业科学家的专业发展。的 候选人组建了一个由经验丰富的独立研究人员和临床医生组成的指导团队， 在拟议的研究目标和指导的成功历史的专业知识。知识分子和物质 匹兹堡大学提供的资源，结合拟议的导师团队的指导 为候选人提供强有力的职位，以实现其提出的培训、研究和职业目标。
