催产素(OT)已成为自闭症谱系障碍(ASD)研究的热点。ASD的社会缺陷的特点可能与减少大脑网站之间的连接中脑边缘的奖励途径(核杏仁核),接受OT的预测,并有助于社会动机,和皮质网站参与社会感知。使用功能性磁共振成像和随机,双盲,安慰剂对照的交叉设计,我们表明,OT管理ASD增加大脑区域的活动,重要的是感知社会情感信息。此外,OT增强了大脑奖励和社会情绪处理系统节点之间的连接,并且优先用于社会(相对于非社会)刺激。这种效应在观察连贯与混乱的生物运动时,以及在听快乐与愤怒的声音时都能观察到。我们的研究结果表明,鼻内OT可以增强社会动机的机制,在未来,可以利用它来增强ASD的行为治疗。
Oxytocin (OT) has become a focus in investigations of autism spectrum disorder (ASD). The social deficits that characterize ASD may relate to reduced connectivity between brain sites on the mesolimbic reward pathway (nucleus accumbens; amygdala) that receive OT projections and contribute to social motivation, and cortical sites involved in social perception. Using functional magnetic resonance imaging and a randomized, double blind, placebo-controlled crossover design, we show that OT administration in ASD increases activity in brain regions important for perceiving social-emotional information. Further, OT enhances connectivity between nodes of the brain’s reward and socioemotional processing systems, and does so preferentially for social (versus nonsocial) stimuli. This effect is observed both while viewing coherent versus scrambled biological motion, and while listening to happy versus angry voices. Our findings suggest a mechanism by which intranasal OT may bolster social motivation—one that could, in future, be harnessed to augment behavioral treatments for ASD.
