olfactory cues

Olfactory cues are signals or information conveyed through smells. They help animals and humans identify, locate, or respond to sources in the environment—such as food, predators, or mates—by detecting specific odors. These cues are processed by the sense of smell in the nose and brain, influencing behaviors and reactions. For instance, the scent of something sweet might attract a person, while a predator's scent could trigger caution. Olfactory cues are essential for survival and social interactions, shaping responses based on the chemical signals detected from surroundings or other individuals.
