Each of Your Nostrils Smells The World Uniquely, Study Reveals
Thanks to our clever brains, it's not immediately noticeable to us, but our two nostrils are actually working independently in some ways and appear to have their own separate sense of smell.
That's the conclusion of a new study from researchers in the US that could teach us much more about the brain and how senses are processed.

“Mechanisms and functions of respiration-driven gamma oscillations in the primary olfactory cortex”
González et al. 2023 https://elifesciences.org/articles/83044

“respiration drives gamma oscillations in the piriform cortex, which correlate with local feedback inhibition… [oscillations] locally segregate neuronal assemblies through a winner-take-all computation leading to sparse odor coding during each breathing cycle.”

Mechanisms and functions of respiration-driven gamma oscillations in the primary olfactory cortex

Computational analyses of in-vivo cerebral activity show that gamma oscillations in the olfactory cortex originate from local feedback inhibition following each sniff and serve to segregate competing odor representations through a winner-take-all process, providing an optimal window to decode odor.
