Electrode is installed in each of the sciatic nerve (Biceps femoris nerve, Common peroneal nerve, and Tibial nerve) divided into three so that the action potential that generated when rats move the hind limb is measured. When parameters of the measured action potential (Activity time, Max potential, Min potential, and Potential difference) were compared, the parameters of the action potential measured from three nerves were same range. The frequency distributions that result of analysing the action potential by FFT are similar in the three nerves. A similar action potential can be detected according to the activity time and the feature of the frequency distribution though there is a difference in the value of measured max potential, min potential, and potential difference when action potentials measured by the hook electrode and the underground electrode are compared. The action potential becomes a similar shape of waves to both Biceps femoris nerve, Common peroneal nerve, and Tibial nerve. Therefore, it is necessary to divide the sciatic nerve when the electrode is installed in sciatic nerve, and to distinguish which nerve it is.

将电极安装在分成三部分的坐骨神经（股二头肌神经、腓总神经和胫神经）中，从而测量大鼠移动后肢时产生的动作电位。当比较测量的动作电位参数（活动时间、最大电位、最小电位和电位差）时，三个神经测量的动作电位参数处于相同范围。通过 FFT 分析动作电位的结果的频率分布在三个神经中是相似的。钩状电极和地下电极测得的动作电位虽然存在差异，但根据活动时间和频率分布的特点，可以检测到相似的动作电位。动作电位与股二头肌神经、腓总神经和胫神经均呈相似形状的波。因此，在坐骨神经安装电极时，需要对坐骨神经进行划分，并区分是哪根神经。
