| Research Abstract |
We have developed a transparent electrode for detecting electrocorticogram simultaneously from optical recording area. We have designed shape of the contact face of the electrode base to a comparable curvature to fit the surface of the adult rat cerebral cortex, and finally we used a glass plano-concave lens for an electrode base. Ga doped ZnO film, a transparent conductor, was deposited on the curved surface and covered with SiO_2 film except some dots. As a result, some halls on the curved surface were remained as the only exposed conductor, and they eventually served as independent electrodes. Using this electrode, we succeeded in decreasing the artifact originated heartbeat pulse on the optical signals.
