Project Summary / Abstract Alcohol use disorder (AUD) is one of the leading causes of preventable death in the United States. AUD is a chronic relapsing disorder that is associated with loss of control and compulsive drinking. The emergence of negative emotional states during acute withdrawal and their maintenance during protracted abstinence are critical driving forces that lead to excessive and compulsive-like alcohol drinking. Identifying the neurocircuitry that is involved in negative emotional states and excessive alcohol drinking is a critical step to understanding the neuronal causes of compulsive alcohol drinking. We have already identified several key brain regions that are recruited during acute alcohol withdrawal, but still unknown is whether these circuits are different during protracted abstinence. Additionally, previous research has often been biased by the preselection of regions of interest; therefore, unbiased whole-brain functional circuitry imaging is a critical step to examine the entire brain and identify entire networks that are involved in alcohol withdrawal. I will utilize the whole-brain imaging of immediate early genes to identify brain regions that are recruited during acute alcohol withdrawal and protracted abstinence. Once these brain regions are identified, they will be compared with regard to functional relationships using correlational analyses and graph theory. These analyses will identify critical components (brain regions) of the functional network of acute alcohol withdrawal and protracted abstinence. These critical components or hubs, once identified, will be targeted and selectively inactivated using the Daun02/LacZ approach to test causal relationships between these hubs and negative emotional states and compulsive alcohol drinking in dependent mice. These studies will be started at The Scripps Research Institute during my K99 phase and completed at my future institution during my independent R00 phase. During my K99 phase, I will receive training in graph theory analyses and Daun02 inactivation to identify and disrupt critical nodes within the functional network of alcohol abstinence. During the R00 phase, I will use Daun02 inactivation to continue these projects and further explore the ways in which the disruption of critical nodes within the functional alcohol abstinence network changes alcohol-related behavior. Collectively, this work will provide insights into the functional circuitry that contributes to alcohol addiction, reveal novel targets and testable hypotheses for future brain imaging studies in human, and facilitate the development of novel treatments for AUD, including targets for noninvasive brain stimulation.

项目总结/摘要 酒精使用障碍（AUD）是美国可预防死亡的主要原因之一。AUD是一个 一种与失控和强迫性饮酒有关的慢性复发性疾病。的出现 急性戒断期间的负面情绪状态及其在长期禁欲期间的维持， 导致过度和强迫性饮酒的关键驱动力。识别神经回路 这是了解消极情绪状态和过度饮酒的关键一步 强迫性饮酒的神经根源我们已经确定了几个关键的大脑区域， 在急性酒精戒断期间被招募，但仍然不知道这些回路在急性酒精戒断期间是否不同。 长期禁欲此外，以前的研究往往是有偏见的预选区域， 因此，无偏见的全脑功能电路成像是检查整个脑功能的关键步骤。 大脑和识别参与酒精戒断的整个网络。 我将利用全脑成像的即时早期基因，以确定大脑区域， 在急性酒精戒断和长期禁欲期间。一旦这些大脑区域被识别出来， 使用相关性分析和图论对函数关系进行比较。这些 分析将确定急性酒精戒断功能网络的关键组成部分（大脑区域） 和长期禁欲一旦确定这些关键组成部分或枢纽， 使用Daun 02/LacZ方法灭活，以检测这些枢纽与阴性之间的因果关系 情绪状态和强迫性饮酒。 这些研究将在我的K99阶段在斯克里普斯研究所开始，并在 在我独立的R 00阶段，我未来的机构。在我的K99阶段，我将接受图形培训 理论分析和Daun 02失活，以识别和破坏功能网络中的关键节点， 戒酒在R 00阶段，我将使用Daun 02灭活来继续这些项目，并进一步 探索如何破坏戒酒网络中的关键节点， 改变与酒精有关的行为。总的来说，这项工作将提供深入了解功能电路， 有助于酒精成瘾，为未来的脑成像研究揭示新的目标和可检验的假设 在人类中，并促进AUD的新治疗方法的开发，包括非侵入性脑靶点 刺激.
