In this paper, Tube-shaped neural probe which has 8 recording areas and 3 optical emitting points using with optogenetics technique for neural circuit analysis has been developed. Outer diameter of tube is 360 μm, the recording areas and the optical emitting points arranged in a depth direction. The optical emitting points make it possible to stimulate neurons in various depth areas respectively. We demonstrated the recording and stimulating of neurons in vivo experiment. As the result, the probe got light induced neural activities at all the optical emitting points.
