|The sense of smell, or olfaction, is closely related to the sense of taste. Chemicals from food or floating in the air are sensed by olfactory receptors in the nose. These signals are sent directly to the olfactory bulb in the olfactory cortex of the brain. There are over 300 different receptors that each bind a specific molecule feature. Each odor contains combinations of these features and binds to different receptors with varying strengths. The totality of these signals are what is recognized as a particular smell. Unlike most other receptors, olfactory nerves die and regenerate regularly.
Research has found if you are still smelling your strawberries you are less likely to experience Alzheimers Disease.
