The present invention relates to a system for detecting a brain nerve activity signal of an animal model, and an automatic control method using the same. The system for detecting a brain nerve activity signal of an animal model comprises: a pair of light sources which are installed on one side of a sensing unit and are spaced from each other at a predetermined interval; a photographing unit, installed on the top of the light sources, for photographing the light sources at a constant cycle for a preset time period and obtaining a plurality of images of the light sources; a rotational connector which is rotatably disposed between the sensing unit and a brain nerve activity signal storage unit and is electrically connected to the sensing unit and the brain nerve activity signal storage unit; a rotational force provision means of which one end is connected to one end of the rotational connector so as to provide a rotational force to the rotational connector; a photographing unit, installed on the top of the light sources, for photographing the light sources and obtaining images of the light sources; and a processor for analyzing the plurality of images obtained by the photographing units, computing rotation information with respect to the rotational direction and rotational angle of the light sources, and controlling the rotational force provision means on the basis of the computed rotation information. The present invention rotates, in response to the number of rotations of an animal model, the rotational connector connected to a cable even when the animal model, which can freely move, rotates and the cable is rotated together. Thus, the present invention has effects of preventing the cable from being twisted and also preventing the movement of the animal model from being interrupted due to the twisting of the cable.
