DESCRIPTION (provided by applicant): The oxytocin (OT) system is arguably the most viable target for pharmacologically enhancing social cognition in psychiatric disorders with compromised social cognition, including autism spectrum disorder (ASD). Central OT enhances key aspects of social behavior in animals, and intranasal (IN) OT modulates social cognition in humans. The mechanisms by which OT affects social cognition are not understood. We will launch a coordinated, interdisciplinary research program involving an outstanding team of investigators to test the hypothesis that OT enhances social cognition by increasing the salience and reinforcing value of social stimuli by modulating activity and functional connectivity of the amygdala and brain regions involved in reward. Project scientists will use cutting edge techniques to assess functional connectivity between brain regions during social interactions, responses of individual neurons in the amygdala to social stimuli, or social cognition in animals and humans. Projects 1 and 2 will use in vivo electrophysiology to examine the impact of OT on the neural representation of social stimuli in rodents and rhesus macaques. Project 3 will use cognitive tests to examine the impact of OT on social perception and social attunement in the primate. Project 4 will use cognitive testing and fMRI to examine the impact of OT on social cognition and neural activity in healthy and autistic humans. A Neurochemistry Core will provide vital services for the research projects and develop new tools for characterizing OT receptor expression in the brain. An Administrative Core will coordinate all Center related activities (seminar series, organizing meetings), will provide statistical consultation and coordinate outreach and training activities of Center personnel by strengthening existing relationships and forging new relationships with numerous organizations in the Atlanta area. As a result, the Center will create vibrant collaborative research, training and outreach environment that will have a national impact on mental health research. The data collected by Center faculty will have important translational implications that will directly impact novel strategies for pharmacologically treating social deficits in psychiatric disorders.

描述(由申请人提供)：催产素(OT)系统可以被认为是在包括自闭症谱系障碍(ASD)在内的社会认知受损的精神疾病中，通过药物增强社会认知的最可行的目标。中枢催产素增强了动物社会行为的关键方面，鼻腔催产素调节人类的社会认知。OT影响社会认知的机制尚不清楚。我们将启动一项协调的跨学科研究计划，由一支杰出的研究团队参与，以测试OT通过调节杏仁核和参与奖励的大脑区域的活动和功能连接来提高社会刺激的显着性和强化价值来增强社会认知的假设。项目科学家将使用尖端技术来评估社会互动期间大脑区域之间的功能连接，杏仁核中单个神经元对社会刺激的反应，或动物和人类的社会认知。项目1和2将使用体内电生理学来检查催产素对啮齿类动物和恒河猴社会刺激神经表征的影响。项目3将使用认知测试来检验催产素对灵长类动物的社会知觉和社会协调的影响。项目4将使用认知测试和功能磁共振成像来检查OT对健康和自闭症患者的社会认知和神经活动的影响。神经化学核心将为研究项目提供重要服务，并开发新的工具来表征大脑中OT受体的表达。行政核心将协调所有与中心有关的活动(研讨会系列、组织会议)，将提供统计咨询，并通过加强现有关系和与亚特兰大地区的许多组织建立新的关系，协调中心人员的外联和培训活动。因此，该中心将创造充满活力的合作研究、培训和推广环境，这将对全国的心理健康研究产生影响。中心教职员工收集的数据将具有重要的翻译意义，将直接影响以药物治疗精神障碍中的社会缺陷的新策略。
