Our long-term memory stores the odors we smell as a mental diorama. The olfactory bulb in the brain makes connections with many other brain regions. Associated details such as emotions, people, locations, plants, animals, etc., are stored with it.
Isn’t it strange how some smells—even quite ordinary ones—can trigger particular memories? Everyone has that one smell that takes them back through time, reminding them of an experience they once had. Smells, as it turns out, are very important to how we remember things.
Our long-term memory stores the odors we smell as a mental diorama. Associated details such as emotions, people, locations, plants, animals, etc., are stored with it. It’s as if the brain makes a mnemonic of that experience using the smell as a key. Smelling such odors again will trigger the recollection of that particular situation. This phenomenon is also termed ‘olfactory memory’.
Applied practically, subjecting people to certain smells will cause them to recollect happy memories. This can be used as a therapeutic approach. That feel-good mood we experience while reminiscing in the past has beneficial effects. It bolsters self-esteem and elevates optimism. The connection between one’s past and present grows stronger.
