Studies have shown that memories are caused by odors are more vivid and emotional than those triggered by sounds, pictures or words.
In order for thoughts to move us to the events of the past, there is nothing better than the smell: whether it’s the scent of mum’s perfume or the salty sea air. The connection between memory and odour is well known. For example, the aromas of barbecue and freshly cut grass can return for the summer days and the smell of pine needles is reminiscent of Christmas.
Scientists believe that this is due to the fact that our brain processes smells in a special way. The so-called olfactory bulb starts in the nose and goes to the lower part of the brain. It is associated with two brain regions – the amygdala and hippocampus, which are actively involved in processing memories and emotions.
Interestingly, visual, audio and touch signals do not pass through these areas of the brain. This may explain why we have such a strong reaction it is on familiar flavors. Researchers from the University of Toronto have found that this is due to the fact that information about time and space is stored in the same area of the brain that processes odors.
That is why specific scents can also be used to enhance performance and improve memory.
