The olfactory system plays a crucial role in our ability to smell, which is closely tied to memory and emotion. In the recent discussion, we explored how the olfactory system functions, starting with a compelling case study of a man named Daniel who experienced anosmia—the loss of smell—after a head injury.
The anatomy of the olfactory system includes structures like the nasal cavity, olfactory epithelium, and olfactory bulb. The nasal cavity serves as the passage for inhaled air, while the olfactory epithelium contains specialized neurons called olfactory receptor neurons (ORNs) that detect odorants.

Additionally, the molecular mechanism of smell detection was discussed, detailing how odorant molecules bind to G-protein-coupled receptors on olfactory cilia, triggering a chain reaction that leads to the generation of action potentials.
Adaptive responses such as olfactory adaptation were also highlighted, explaining how prolonged exposure to a smell can decrease sensitivity. Understanding the neural pathways, we learned that olfactory signals bypass the thalamus and go straight to emotional centers in the brain, which explains the strong connection between smell, memory, and emotion.

Moreover, clinical correlations such as anosmia, hyposmia, and their implications, particularly in cases like viral infections (e.g., COVID-19) affecting smell, were important points in our discussion.
