| Research Abstract |
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.
