Which sense is closely linked to memory and emotion?

The sense that is closely linked to memory and emotion is smell. This connection can be attributed to the anatomy of the brain and the specific pathways involved in olfaction. When odors are detected by the olfactory receptors in the nose, the signals they send are processed by the olfactory bulb, which is situated near the limbic system—an area of the brain that plays a significant role in emotional responses and memory formation.

Because of this proximity, scents often evoke vivid memories and strong emotions, more so than other senses. For example, a particular smell might remind someone of a childhood memory or elicit feelings of nostalgia. This is why certain fragrances can trigger emotional responses or bring back significant memories with remarkable clarity, demonstrating the unique link between olfaction, emotion, and memory.

In contrast, while taste, sound, and vision are also closely connected to various experiences, their neural pathways do not interact with the limbic system in the same direct manner as smell. This makes olfaction particularly distinctive in its association with memory and emotion.
