With EthoVision XT and the Social Interaction Module, you can automatically track multiple animals in an arena. But for work with rats and mice you can do more if you also have the Multiple Body Points Module. Then you can for example analyze how often and how long the nose point of one animal has been near the tail base of the other animal. This way you can, for example investigate sexual behavior.
With EthoVision XT’s Trial & Hardware Control Module your possibilities become even larger. You can control hardware when your animals show a certain behavior together. You can, for example, give a cue when one animal’s nose point is in proximity of the tail base of the other animal. Or you can automatically carry out cooperation studies by giving a food reward when both animals are in a certain zone together. This opens doors for a wide variety of automated social interaction studies.
