Treatment for alcohol use disorders (AUD) is a research priority, and innovative treatment approaches are needed. The goal of this application is to investigate an innovative technology that targets a brain region, rather than a medication, for AUD. Using repetitive transcranial magnetic stimulation (rTMS) with a newly developed coil that can reach deeper brain regions (the H coil), this proposal will study the effects of deep rTMS directed at the dorsolateral prefrontal cortex, medial prefrontal cortex and anterior cingulate. Previous imaging studies heavily implicate these brain regions in AUD, and show that their dysregulation is associated with impaired decision-making, risky drinking, and weak performance on attention-demanding tasks. We will use the H7 coil, which reaches deeper and wider regions of the prefrontal cortex. Subjects with AUD (moderate to severe) will undergo alcohol self- administration sessions before and after rTMS. Subjects will be randomly assigned to high frequency active rTMS (n=16, 8M/8F) vs sham (n=16, 8M/8F). The primary outcome measure will be the amount of alcohol consumed in alcohol self-administration sessions, a laboratory model of alcohol seeking behavior, which also provides measures of craving and the subjective effects of alcohol.

酒精使用障碍（AUD）的治疗是一个研究重点， 是必要的。这项应用的目标是研究一种针对大脑的创新技术 地区，而不是一种药物，为澳元。使用重复经颅磁刺激（rTMS） 利用新开发的可以到达更深大脑区域的线圈（H线圈），该提案将研究 针对背外侧前额叶皮层、内侧前额叶皮层和 前扣带以前的成像研究严重牵连这些大脑区域在澳元，并显示 他们的失调与决策障碍、危险饮酒和虚弱有关。 在需要注意力的任务上的表现。我们将使用H7线圈，它可以达到更深更宽的范围 前额皮质的区域。患有AUD（中度至重度）的受试者将接受酒精自我治疗。 在rTMS之前和之后的管理会话。受试者将被随机分配到高频率 活动rTMS（n=16，8 M/8 F）与假手术（n=16，8 M/8 F）。主要结果指标将是 在酒精自我管理会议中消耗的酒精，酒精寻求的实验室模型 行为，这也提供了渴望和酒精的主观影响的措施。
