Researchers Discover Neural Circuit for Detecting Male Pheromone Cues Relevant to Inter-male Aggression

In a study published in Neuron, the researchers from Dr. XU Xiaohong’s Lab at the Institute of Neuroscience, Center for Excellence in Brain Science and Intelligence Technology of the Chinese Academy of Sciences, described a novel neural circuit for detecting male pheromone cues pertaining to inter-male aggression.
Innate social behaviors are crucial for the propagation of a species. Yet, before launching any consummatory actions, animals need to first integrate sensory information to determine the sex of the interacting conspecifics. For example, males mate towards females but attack other males.
