Smell is one of our most sensitive senses and is most closely related to our memories and feelings. It plays such an important role in our brain. Our olfactory bulb starts inside the nose and runs along the bottom of the brain, where it is the first stop for new smells. The bulb is directly connected to two areas
of the brain that control emotion and memory: the amygdala and hippocampus. Scientists believe that our sense of smell triggers memories more than other senses because these senses do not pass through these areas of the brain. Memories triggered by our sense of smell can be
accompanied by clear images and feelings of happiness, excitement, pain, and despair. For example, the perfume industry is built around this connection, with perfumers developing fragrances that seek to convey a vast array of emotions and feelings; from the desire to power, vitality to relaxation.
