Researchers have found in a survey that for many people, the sense of smell is considered less important than sight, hearing, and other physical traits. However, the sense of smell plays a significant role in several ways.
Half of the women surveyed reported that they would prefer to have a stronger sense of smell than a better sense of sight. The sense of smell is one of the first sensory systems connected to your brain health, memory, and other mental functions.
It is directly linked to both memory and emotions. This connection was first discovered by American psychologist Donald Laird in 1935. Any scent is initially recognized by special nerve cells in the nose, which then transmit the signals to the brain’s olfactory bulb. From there, the signals are directly linked to the limbic system of the brain, which includes the amygdala, where emotions are generated, and the hippocampus, where memories are stored.
On the other hand, other senses like sight and hearing are not directly connected to the limbic system.
