Research has revealed that a molecule involved in fish reproduction activates the brain via the nose. The pheromone is released by female zebrafish and sensed by smell receptors in the noses of the males. The neural pathway and brain areas involved in transforming this molecular messenger into courtship behavior in fish were also identified by the researchers.
