社会威胁安全测试允许同时评估社会回避发展,作为厌恶条件学习和社会威胁安全辨别能力的测量,两者都用于在一组长期社会失败的雄性小鼠中识别压力易感和压力弹性个体。

我们的研究旨在揭示压力弹性的潜在机制。通过了解这些机制,我们可以利用它们来制定更好的治疗策略,以应对与压力相关的精神障碍和预防。我们的研究开发了一种具有高面部有效性的新小鼠模型,该模型允许将一组应激小鼠分层为基于恐惧回路的弹性和易感性相关表型。

此外,我们还为全球复原力机制的存在提供了证据。我们对应激小鼠的研究表明,它们表现出表明人类适应力和易感性的特征。具体来说,它们在威胁安全鉴别和对灭绝的反应方面表现出不同的能力,这是与复原力相关的关键特征。

我们在小鼠中发现的弹性和易感性相关表型具有面部有效性,并且基于恐惧回路。这种回路在物种之间是高度保守的,可以说是研究得最好的回路之一。反过来,这允许有可能为治疗、开发和预防措施做出贡献的机制研究。

我们将使用我们的新模型来更深入地挖掘弹性的神经生物学机制,并了解如何积极促进弹性。此外,我们将采用纵向分析来判断个人复原力如何随着时间的推移而发展。
