[Abstract]  The brainstem-spinal cord preparation of newborn rat contains neural networks able to produce motor output in absence of sensory feedback. These neural structures, commonly called central pattern generators (CPGs), are involved in many vital functions such as respiration (Morin and Viala, 2002; Giraudin et al., 2008) or locomotion (Juvin et al., 2005). Here we describe a procedure for the isolation of the brainstem-spinal cord tissue of neonatal rat (0-2 days old). A surgical method under binocular microscope allows the brainstem and the spinal cord to be isolated in vitro and the motor outputs to be recorded. This preparation can then be used for diverse experimental approaches, such as electrophysiology, pharmacology or anatomical studies, and constitutes a ... [摘要]  新生大鼠的脑干 - 脊髓制备包含能够在没有感觉反馈的情况下产生运动输出的神经网络。 这些神经结构,通常称为中枢模式发生器(CPG),涉及许多重要功能,如呼吸(Morin和Viala,2002; Giraudin等,2008)或运动(Juvin等,2005)。 在这里,我们描述了分离新生大鼠脑干脊髓组织(0-2天)的程序。 双目显微镜下的手术方法允许脑干和脊髓在体外被分离,并且马达输出被记录。 然后,该制剂可用于多种实验方法,例如电生理学,药理学或解剖学研究,并且构成研究CPG之间相互作用的有用模型(Juvin等人,2007; 2012; Giraudin等,2012; Le Gal 等人,2014; 2016)。
【背景】历史上,开发了新生儿啮齿动物的体外脊髓来研究脊柱反射(Otsuka和Konishi,1974)。 1984年,Suzue率先开发出新生大鼠的体外脑脊髓脊髓制剂。因此,有可能证明孤立的中枢神经系统能够自发产生所谓的虚构的呼吸活动。之后,可以确定运动员节奏生成所依赖的CPG的位置(Cazalets等,1995; Kjaerulff和Kiehn,1​​996; Ballion等,2001)和那些从事呼吸节律生成(Smith et al ,1991; ...
