Olfactory Neurogenesis Insights

Stem cells produce neuroblasts that migrate to the olfactory bulb, highlighting the unique ability of olfactory neurons to regenerate throughout life. Factors like exercise, social interactions, and exposure to different odors can enhance this neurogenesis. Interestingly, dopamine plays a crucial role in the formation of new neurons and their migration, influencing the sense of smell, though a poor sense of smell doesn't necessarily indicate low dopamine levels.
