Smell and Memory
It’s the middle of winter, but you are going to be out in the sun all day, so you pull out your bottle of sunscreen and pour some into your palm. Suddenly, the tropical sunscreen smell makes you think of summer, and digging your toes into warm beach sand. Why do some smells link to specific memories?
The olfactory bulb that recognizes smells is part of the limbic system, which is the part of the brain that deals with emotion, memory, and feelings. When you smell things, the olfactory bulb talks to the rest of the system, allowing your brain to make a connection between the smell and what you’re feeling or experiencing at the time. That’s why childhood experiences are often brought back up when you smell something you encountered at an early age, and why people often like different sets of smells.
The limbic system isn’t the only one that talks to the olfactory system. In fact, flavor is a combination of your sense of smell and your sense of taste. Your brain combines the sensations to give a more unique recognition of the food you are tasting. Some animals, like mice, have brains that will combine sounds and smells to allow them to better sense the world around them.
