Understanding the Limited Focus on Olfaction in Neuroscience

By Abinaya Srinivasan 

For many years, vision and memory have dominated neuroscience research and public attention. In comparison, the olfactory system is often viewed as secondary, despite its strong connections to emotion, memory, behavior, and neurodegenerative diseases. Recent research has shown that olfactory dysfunction is becoming an early indicator of disorders such as Alzheimer's and Parkinson's. Yet, compared with other sensory systems, olfactory neuroscience still appears to receive less attention in both research discussion and clinical translation. I believe this raises an important question about whether the neuroscience community may be underestimating the broader significance of the olfactory system. 

Share your thoughts on the topic below and use these guiding questions to get started:

• In neuroscience, should olfaction research be prioritized over visual and memory research?
• What significant barriers prevent olfactory research from entering mainstream clinical practice?
• Should olfactory dysfunction play a larger role in early neurological screening?
