Video 1: Submerged platform with visible marker TRAINING Video 1: Submerged platform with visible marker The platform has four poles with black-and-white stripes that serve as visible markers for the rat. You cannot see the poles because they are covered by a plain grey top. This is to ensure that the tracking software, which the camera feeds into, only tracks the swimming rat, not the poles.
