Below is a link to a recent article about some new research into pheromone receptors. Interesting.
“Humans no longer have a functional vomeronasal system…”
Yet…pheros still work…hmmmm…
Must be another pathway…
Androsterone is a neurosteroid ligand that binds in the brain to receptors, producing sedation; no such ligand/receptor pairs are expressed in human olfactory epithelium (nose), although hundreds of receptors for the musk smell of pheromones are.
