pheromone

Chemically, the snail’s mimics are actually more stable than the worm’s natural pheromones, which degrade relatively quickly after release, Torres says.

This organ detects pheromones produced by others of the same species and then sends cues to the brain to mate, attack or do other things.

When I was a junior faculty member at Harvard, we wondered what would happen if we eliminated the cues to the brain from pheromones.

Relatively early in her career, Dulac’s investigations into how animals detect pheromones changed our understanding of what those airborne chemicals may signify to the brain.

Surprisingly, without the cues from pheromones, we saw females behaving like males.

I have looked over high-tech dog collars loaded with a behavior-regulating pheromone.
