"If humans can detect anything in tears, we won't use the same pheromone signal or receptor as mice. But we are investigating if species share the basic neurocircuitry of how the brain processes an olfactory signal to affect behavior," said Professor Kazushige Touhara, leader of the research project.

Researchers hope to use the tear pheromone as a natural mouse birth control to reduce mouse populations in the future.
