Feb 5, 2024 Think about smelling cookies baking and being instantly reminded of your childhood and your family's kitchen. Or it could be the smell of sunscreen lotion that takes a person back to hot summer days and playing on the beach. This relationship between the olfactory and the memory is called the Proust Effect in honour of the French writer Marcel Proust, who described the concept in his classic novel Swann's Way.

A Unique Sensory Pathway: This is why smells effectively evoke memories.

While the other senses, like vision and hearing, are transmitted by the thalamus, the sense of smell has a more straightforward path to the brain. Specifically, odour molecules enter the nose and then go directly to the olfactory bulb in the brain's limbic system, which is the emotional centre. This is because the olfactory bulb is located near the amygdala, the part of the brain that processes emotions and forms memories. This is why smells can bring powerful and emotional memories to mind.

A Sensory Shortcut: Skipping Logic and Outpouring a Flood of Memories

Dodging memories based on vision or sound, which the latter usually involves some rational analysis, is not necessary; smells can directly activate memories. A scent can easily take you back to a certain point in your life, including visual images, noises, feelings, and even physical feelings at that time. This is because the scent we experience is typically related to specific events in childhood, which is a period of high sensibility of the human brain to stimuli.
