| Outline of Final Research Achievements |
We have developed two apparatuses. One is mechanical stimulator and the other is transparent electrode for electrical stimulation. These are commercially available for electrophysiological experiments, but neither of them can be applied to the experiment using optical technique. The problem of the former is physical oscillations it produces. By introducing a pair of neodymium magnets we succeeded in reducing the oscillations without spoiling high precision in the position. Concerning the latter, we had already developed a transparent electrode for electrical recording which can be used in the recording area during optical measurement. However, when applied to stimulation, the transparent conductive film made of Ga doped ZnO (GZO) is broken due to the heat caused by the stimulus current. We solved this problem by reducing the electrical resistance of the conductive part. The GZO film was covered with the film made of Nb doped TiO2 (NTO) (NTO), followed by annealing process.
