Nose stimuli, also known as olfactory stimuli, are the smells that stimulate the sense of smell. ODORS are one type of nose stimuli, which are molecules in the air that can be detected by the nose. Other types of nose stimuli include pheromones, which are chemicals secreted by animals and humans that can affect behavior, and taste-smell conjugates, which are combinations of tastes and smells that can create unique flavor experiences.
