Basal cells are the receptor cells located in the olfactory epithelium that detect specific chemicals in the air and transduce them into a neural signal.

Stu cooked two wild pigs over a fire outside his restaurant.The first night, he cooked one of the pigs and told customers the aroma was a wild swamp pig, and most of them asked to sit away from the smoking area because it smelled disgusting.The second night, he cooked the other pig the same way and told customers he was cooking free-range organic pork.Those customers asked to sit nearer the smoking area so they could take in the rich aroma.Briefly explain what has happened to Stu's customers' olfactory perceptions.
