Scent detection refers to the ability to identify and differentiate various odors using the sense of smell. This skill is commonly utilized in fields such as law enforcement, where trained dogs can locate drugs or explosives, and in medical diagnostics, where certain diseases can be detected through specific scents emitted by the body. The process involves specialized receptors in the nose that send signals to the brain, allowing individuals or animals to recognize and interpret different smells. Scent detection is also important in food industry quality control, where it helps ensure products meet safety and freshness standards.
