Olfactory neurogenesis

Olfactory neurogenesis is the natural process by which the brain produces new neurons in the olfactory system, responsible for our sense of smell. Located in the nasal cavity, specialized stem cells continuously generate new olfactory sensory neurons that detect odors. These new neurons integrate into existing neural circuits, allowing for the maintenance of a keen sense of smell throughout life. This ongoing regeneration is essential because olfactory neurons have a limited lifespan and are exposed to potential damage from environmental factors like pollutants. Overall, olfactory neurogenesis helps sustain our ability to perceive odors reliably over time.
