This Girl On TikTok Has Had Parosmia For Almost A Year

“Think of it like this. The entire olfactory system, or your sense of smell, is a computer. The brain is the CPU of the computer, or the main memory. The keyboard is what’s in our nose. And the keys on the keyboard are neurons, which are able to catch the odors,” she told BuzzFeed. “What happens with parosmia is essentially that the keys are jumbled up and placed in the wrong positions. So when an odor comes into the nose, the neurons send the wrong signal to the brain.”
