olfaction

Olfaction, or the sense of smell, involves detecting airborne molecules through specialized receptors in the nose. When you inhale, molecules from food, scents, or environments bind to these receptors, triggering signals to the brain. The brain then processes these signals to identify and interpret different odors, which can influence emotions and memories. This complex system allows us to enjoy flavors, detect hazards like smoke or spoiled food, and experience a wide range of sensory information about our surroundings.
