我们借鉴了变稳态的理论,开发了一个综合模型,目前的压力过程,突出了大脑作为一个动态适应不断变化的环境和生物自我之间的接口。我们回顾的证据表明,大脑的核心情感区域构成了压力和健康之间的良好关系的主要调解人,以及由于持续的适应“磨损”的神经焦点。反过来,这种中介作用使我们能够模拟环境、当前压力源暴露、身体过程的内部调节和健康结果之间随着时间的推移而发生的相互作用。我们说明了这种方法如何促进人类神经科学和遗传学的当前研究结果与社会和生命科学压力模型的关键结构的整合,并对未来的研究和针对风险个体的干预措施的设计产生影响。
We draw on the theory of allostasis to develop an integrative model of the current stress process that highlights the brain as a dynamically adapting interface between the changing environment and the biological self. We review evidence that the core emotional regions of the brain constitute the primary mediator of the well-established association between stress and health, as well as the neural focus of “wear and tear” due to ongoing adaptation. This mediation, in turn, allows us to model the interplay over time between context, current stressor exposure, internal regulation of bodily processes, and health outcomes. We illustrate how this approach facilitates the integration of current findings in human neuroscience and genetics with key constructs from stress models from the social and life sciences, with implications for future research and the design of interventions targeting individuals at risk.
