Spared Nerve Injury Model of Neuropathic Pain in Mice

[Abstract]  Experimental models of peripheral nerve injury have been developed to study mechanisms of neuropathic pain in living animals. The spared nerve injury (SNI) model in rodents is a partial denervation model, in which the common peroneal and tibial nerves are injured, producing consistent and reproducible tactile hypersensitivity in the skin territory of the spared, intact sural nerve. SNI-operated mice require less force applied to the affected limb to elicit a withdrawal behavior as compared to sham mice. This effect is observed as early as 2 days after surgery and lasts for at least 1 month. We describe detailed surgical procedures to establish the SNI mouse model that has been widely used for investigating mechanisms of neuropathic pain.

[Abstract]  A memory trace, also known as a memory engram, is theorized to be a mechanism for physical memory storage in the brain (Silva et al., 2009; Josselyn, 2010) and memory trace is associated with a specific population of neurons (Liu et al., 2012; Ramirez et al., 2013). Labeling and stimulating those neurons will activate the memory trace (Liu et al., 2012; Ramirez et al., 2013). Memory appears to be spread over different regions of the brain rather than being localized to one area. Therefore, the methods used to trace memory have the ability to improve our understanding of neuronal circuits. In this protocol, we introduce a doxycycline-inducible expression system to label the specific neurons associated with the original memory trace. [摘要]  存储器跟踪(也称为存储器枚举)被理论化为大脑中物理存储器存储的机制(Silva等人,2009; Josselyn,2010),并且内存跟踪与一个 特定的神经元群体(Liu et al。,2012; Ramirez等人,2013)。 标记和刺激那些神经元将激活记忆痕迹(Liu et al。,2012; Ramirez等人,2013)。 记忆似乎分布在大脑的不同区域,而不是局限于一个区域。 因此,用于跟踪记忆的方法有能力提高我们对神经元电路的理解。 在本协议中,我们引入多西环素诱导表达系统来标记与原始记忆痕迹相关的特定神经元。
【背景】记忆痕迹是记忆被存储为大脑物理或生物化学变化的理论手段(Ryan等人,2015)。在二十世纪初德国动物学家理查德·塞蒙(Richard Semon)制定记忆追踪概念之后,记忆存储的具体过程一直是神经科学领域辩论的一个未解决的话题(Poo et al。,2016)。尽管记忆机制已经成为几十年来的争论焦点,但已经一致认为,特定的神经元被用于记忆的存储(Liu等人,2012; Ramirez等人, ...
