Quizplus · Accepted Answer

The perception of odor strength is related to the frequency of action potentials reaching the brain. When a person smells an odor, it triggers the olfactory receptor neurons in the nose to send signals to the brain. The frequency of these signals determines how strong the person perceives the odor to be. A higher frequency of signals indicates a stronger odor, while a lower frequency indicates a weaker odor.
