Olfactory System: The olfactory system is responsible for our sense of smell. It includes receptors in the nose that detect different odors and send signals to the brain.
Pheromones: Pheromones are chemical substances produced by animals (including humans) to communicate with each other through scent. They can influence behavior or trigger physiological responses.
Conditioning: Conditioning refers to the process of learning associations between stimuli and responses. In the context of aromas, prolonged exposure to a specific aroma can lead to conditioned responses, where we start associating that smell with certain emotions or behaviors.
