Discover the science behind our sense of smell

Uplifted, nostalgic, comforted… our brains are persistent in translating the different smells we encounter every day into feelings. That’s because our noses quickly send signals to different areas of the brain. Which two areas are these? Of all the senses, smell is most directly linked to memory.

By understanding science, scents can be designed to calm or invigorate.

Watching a movie or listening to a song on the radio provokes emotional reactions; it makes you smile, laugh or shed a tear. Our ability to interpret visual or auditory cues generated by movies and songs is due to a sensory process in the brain called “transduction” that converts light and sound into electrical signals that, when combined with chemical neurotransmitters, make up the essence. of how our brains think, feel and behave at all times of the day and night. Our sense of smell is also managed through transduction.

Emotional connection

Smelling is the most fundamental and immediate sense, triggers a profound emotional response from customers and can influence moods, memory and emotions. Onze sense of smell beïnfloods 75% of everyday emotions and plays an important role in memory.

Each sense has its own function in perception. For example, our visual perception is especially suitable for transferring knowledge and smell is closely linked to memory and emotion. In combination, they reinforce each other. Sensory marketing takes advantage of that. If the picture is completely correct, the feeling experience increases enormously.

How we smell

Olfactory region linked to emotion and memory.

The olfactory region of the brain, where smells are processed, is connected to many other brain regions, such as those of emotion (the amygdala), memory (the hippocampus) and the multisensory regions (the orbitofrontal cortex). In fact, our olfactory organ forms a kind of ‘superhighway’ to memories or emotions through its connections. Scented messages are interpreted by all these different parts of the brain to evoke a response in the form of thoughts, feelings and actions.

Scientists are increasingly aware of ways in which the human senses can be harnessed to manage our own well-being – so the scent can now be designed to stimulate the best emotional experience possible; the perfect relaxing scent for a warm bath or for washing sheets to promote a good night’s sleep.
