Why smell is so important

According to Fifth Sense, a charity for individuals affected by olfactory disorders, our olfactory neurons generate an impulse when it detects a smell. The olfactory nerve passes the impulse to a part of the brain known as the olfactory bulb. Here the signal is processed and passed on to related areas of the brain. This is collectively called the limbic system.

The Fifth Sense explains that “The limbic system comprises a set of structures within the brain that are regarded by scientists as playing a major role in controlling mood, memory, behavior, and emotion.” The Khan Academy adds that The limbic system is a set of structures in the brain that deal with emotions and memory. This helps us to realize why smell is so important when it comes to managing our mood, memories, and emotions.
