61 This scent-processing area of the brain is next to the amygdala (the memory creating section of the brain) and the hippocampus (the part of the brain that creates emotions). Most of us can immediately identify at least one smell that makes us smile Vanilla scores high on the list of prefered smells and is a native of South and Central America and the Caribbean; and the first people to have cultivated it seem to have been the Totonacs of Mexico’s east coast. Our sense of smell comes ready and rearing to go from birth – it is fully developed from day one, and is the most active of the five senses until age 10 (when sight takes over). This early development may be why scents affect us so intensely – that and the fact that our sense of smell (unlike our other senses) goes straight to the brain! Ok, mini science lesson: when our sense of taste, sight, hearing and touch receive information – let’s say we touch something hot – our sensory neurons are responsible for getting that message to the brain. However, the neurons make a pit stop at a relay station before the message “this feels hot”, reaches the brain. In contrast, when we smell something, the neurons that carry the scent message travel straight to the brain without stopping at the relay station. Basically our sense of smell has a direct, uninterrupted connection to our brain! When scent reaches the brain it goes to the “olfactory bulb” which is the part of the brain responsible for processing scent. This scent-processing area of the brain is next to the amygdala (the memory creating section of the brain) and the hippocampus (the part of the brain that creates emotions). Unbeknownst to us, our brain associates some scents with particular emotions and memories then locks them away for safekeeping. “Unbeknownst to us, our brain associates some scents with particular emotions and memories THE SENSES ISSUE
