The sense of smell, or olfaction, is primarily processed in the brain's olfactory bulb, which is located in the frontal lobe, just above the nasal cavity. The olfactory pathways are somewhat unique as they do not cross over to the opposite hemisphere like many other sensory modalities. Instead, olfactory signals are processed in both hemispheres, but they are closely linked to areas responsible for emotions and memory, such as the limbic system. Overall, both hemispheres contribute to the perception and processing of smells.

Can brain damage affect the olfactory nerve?

Yes, brain damage can affect the olfactory nerve, which is responsible for the sense of smell. Damage to specific areas in the brain, such as the olfactory bulbs or frontal lobes, can lead to changes in the sense of smell or loss of smell altogether.
