Researchers Claim Pheromones Trigger Brain Cell Growth

The Canadian Broadcasting Corporation is reporting that pheromones could enable the growth of new brain cells. "Pheromone signals from dominant males spark new brain cells in their female partners and could help repair injured brains, suggests a new study by a University of Calgary neuroscientist. Sam Weiss's findings, in the July issue of the journal Nature Neuroscience, provide evidence that pheromones -- subtle chemical signatures that influence mating behavior -- can control stem cells in the brain."
