Nose odors and mouth odors: The brain distinguishes

Researchers found that brain responds differently to odors introduced through the nose versus the mouth, with distinct brain regions activated. The study suggests that olfactory referral illusion is robust and cognitively impenetrable, and may play a role in flavor perception.
