Male mice appear to be precisely wired to know when they are intruders in another male's territory, according to a study published June 23 in Cell Reports. The smell gives it away. But this study found that a genetically specific cluster of hypothalamic cells is wired to the olfactory system and responds only when a male mouse enters another male's cage.
