olfactory pathways

Olfactory pathways are the routes through which smell information is processed in our brains. When we inhale, tiny molecules from scents activate receptors in our nasal cavity. These receptors send signals directly to the olfactory bulb at the base of the brain. From there, the signals are relayed to various brain areas, including the olfactory cortex, which helps identify and interpret smells. This process is unique because it bypasses the thalamus, a relay station for other senses, allowing us to experience smells more directly and emotionally, linking them to memories and feelings.
