Abstract

In nearly all mammalian species, newborn pups are weak and vulnerable, relying heavily on care and protection from parents for survival. Thus, developmentally hardwired neural circuits are in place to ensure the timely expression of parental behaviors. Furthermore, several neurochemical systems, including estrogen, oxytocin, and dopamine, facilitate the emergence and expression of parental behaviors. However, stress can adversely affect these systems, impairing parental behaviors. In this review, we will summarize our current knowledge regarding the impact of stress on pup-directed behavior circuits that lead to infant neglect, abuse, and, in extreme cases, killing. We will discuss various stressors that influence parental behaviors at different life stages and how stress induces changes in the neurochemical systems that support parental care, ultimately leading to its poor performance.

在几乎所有哺乳动物物种中,刚出生的幼崽都是脆弱和易受伤害的,它们的生存在很大程度上依赖于父母的照顾和保护。因此,发育过程中形成的神经回路确保了父母行为的及时表达。此外,包括雌激素、催产素和多巴胺在内的几种神经化学系统也有助于父母行为的出现和表达。然而,压力会对这些系统产生不利影响,从而损害父母的行为。在本综述中,我们将总结目前有关压力对幼崽定向行为回路的影响的知识,这些回路会导致婴儿被忽视、虐待,甚至在极端情况下被杀害。我们将讨论在不同生命阶段影响父母行为的各种压力因素,以及压力如何诱导支持父母照料的神经化学系统发生变化,最终导致其表现不佳。
