[Abstract]  Although it is known that the generation of movements is performed to a large extent in neuronal circuits located in the spinal cord, the involved mechanisms are still unclear. The turtle as a model system for investigating spinal motor activity has advantages, which far exceeds those of model systems using other animals. The high resistance to anoxia allows for investigation of the fully developed and adult spinal circuitry, as opposed to mammals, which are sensitive to anoxia and where using neonates are often required to remedy the problems. The turtle is mechanically stable and natural ... [摘要]  虽然已知在位于脊髓的神经元回路中很大程度地进行运动的产生,但是所涉及的机制仍不清楚。乌龟作为调查脊柱运动活动的示范系统具有优势,远远超过使用其他动物的模型系统。对缺氧的高抗性允许对完全发育和成年脊髓电路进行调查,而不是对缺氧敏感的哺乳动物,并且通常需要使用新生儿来补救问题。乌龟是机械稳定的,天然感觉输入可以诱导多种复杂的运动行为,而不需要神经化学物质的应用。在这里,我们提供了如何使成年龟准备的详细方案,也称为电生理调查的综合准备。在这里,通过机械感觉激活,通过细胞内,细胞外和电图记录来记录单细胞和网络活性,可以诱导后肢刮擦反射。该准备工作是由Petersen等人(2014)和Petersen和Berg(2016)以及其他正在进行的研究开发的。
【背景】脊髓电生理学的研究传统上与机械并发症有关,因为许多运动部件和脊柱的灵活性。为了规避这个问题,脊髓经常从柱中解剖出来并移动到可以进行稳定的电生理记录的室。然而,该过程具有缺点,例如,如果要研究多个电动机行为,则适当激活电动机电路是复杂的。此外,缺乏供血和缺乏氧气对电路的健康和完整性有严重影响。一个可以规避所有这些问题的实验模型是龟制剂(Keifer and ...
