最近的研究表明,青春期为重新调整年轻人的压力反应系统提供了机会,他们对压力的反应已经被早期的逆境改变。这种重新校准可能会产生连锁效应,影响大脑和行为发育。在这篇文章中,我们考虑了大量的跨物种文献,以证明青春期应激重新校准对于理解早期被照顾者剥夺后的精神病理学发展的潜在重要性。我们回顾了人类下丘脑-垂体-肾上腺轴重新校准的证据,审查了对啮齿类动物的研究,这些研究已经建立了应激激素影响大脑结构和功能的机制,并总结了关于人类神经成像的文献,以评估这些机制如何转化为人类行为的变化。最后,我们提出了一些想法来阐明青春期压力重新校准的后果,这将提高我们对早期逆境后适应和适应不良青少年行为的理解。
Recent research has suggested that the pubertal period provides an opportunity for recalibrating the stress-responsive systems in youth whose responses to stress have been altered by early adversity. Such recalibration may have cascading effects that affect brain and behavioral development. In this article, we consider a large, cross-species literature to demonstrate the potential importance of pubertal stress recalibration for understanding the development of psychopathology following early deprivation by caregivers. We review the evidence for recalibration of the hypothalamic-pituitary-adrenal axis in humans, examine research on rodents that has established mechanisms through which stress hormones affect brain structure and function, and summarize the literature on human neuroimaging to assess how these mechanisms may translate into changes in human behavior. Finally, we suggest ideas for elucidating the consequences of pubertal stress recalibration that will improve our understanding of adaptive and maladaptive adolescent behavior following early adversity.
