Olfactory perception refers to the process by which the brain interprets smells. It begins when odor molecules enter the nose and bind to specialized receptors in the olfactory epithelium. These receptors send signals to the olfactory bulb, which processes the information and relays it to other brain areas for further interpretation. This sense plays a crucial role in identifying food, detecting hazards, and influencing emotions and memories. The ability to perceive different odors is essential for survival and can vary significantly among individuals. Factors such as age, health, and genetics can affect one's olfactory perception.
