ArgumentIn this article, we trace shifting narratives of trauma within psychiatric, neuroscience, and environmental epigenetics research. We argue that two contemporary narratives of trauma – each of which concerns questions of time and psychopathology, of the past invading the present – had to be stabilized in order for environmental epigenetics models of suicide risk to be posited. Through an examination of these narratives, we consider how early trauma came to be understood as playing an etiologically significant role in the development of suicide risk. Suicide, in these models, has come to be seen as a behavior that has no significant precipitating event, but rather an exceptional precipitating neurochemical state, whose origins are identified in experiences of early traumatic events. We suggest that this is a part of a broader move within contemporary neurosciences and biopsychiatry to see life as post: seeing life as specific form of post-traumatic subjectivity.

时间、创伤和大脑：自杀如何没有显着的诱发事件

论点在本文中，我们追溯了精神病学、神经科学和环境表观遗传学研究中关于创伤的不断变化的叙述。我们认为，为了建立自杀风险的环境表观遗传学模型，必须稳定两种当代关于创伤的叙述——每一种都涉及时间和精神病理学问题，过去侵入现在。通过对这些叙述的研究，我们考虑了早期创伤如何被理解为在自杀风险的发展中发挥了病因学上的重要作用。在这些模型中，自杀已被视为一种没有显着诱发事件的行为，而是一种特殊的诱发神经化学状态，其起源可在早期创伤事件的经历中确定。生活如岗位：将生活视为创伤后主观性的特定形式。
