关于杏仁核在自闭症中的确切作用,人们一直感到困惑。为了帮助解决这个问题,我们求助于NIMH的研究领域标准(RDoC),它提供了一个分类模式,可以识别不同类别的行为,这些行为可以在心理健康障碍中变成病理性的,例如自闭症。虽然RDoC纳入了所有已知的神经生物学基板的每个域,本次审查将主要集中在杏仁核。我们首先从解剖学、历史学和发育学的角度来考虑杏仁核。接下来,我们研究杏仁核参与的RDoC的不同领域和结构:负价系统,正价系统,认知系统,社会过程,唤醒和调节系统。然后,自闭症的杏仁核功能障碍的证据,重点是在发展中的变化,产前丙戊酸暴露作为ASD的模型,并在催产素系统的变化。最后,综合RDoC,杏仁核,自闭症提供,强调消除歧义的任务和建议,为今后的研究。
Confusion endures as to the exact role of the amygdala in relation to autism. To help resolve this we turned to the NIMH’s Research Domain Criteria (RDoC) which provides a classification schema that identifies different categories of behaviors that can turn pathologic in mental health disorders, e.g. autism. While RDoC incorporates all the known neurobiological substrates for each domain, this review will focus primarily on the amygdala. We first consider the amygdala from an anatomical, historical, and developmental perspective. Next, we examine the different domains and constructs of RDoC that the amygdala is involved in: Negative Valence Systems, Positive Valence Systems, Cognitive Systems, Social Processes, and Arousal and Regulatory Systems. Then the evidence for a dysfunctional amygdala in autism is presented with a focus on alterations in development, prenatal valproic acid exposure as a model for ASD, and changes in the oxytocin system therein. Finally, a synthesis of RDoC, the amygdala, and autism is offered, emphasizing the task of disambiguation and suggestions for future research.
