Connection between language and smell


According to a study conducted by researchers at Stockholm University and Northwestern University in Chicago, language is connected with the sense of smell. The researchers conducted a study where participants decided whether a word such as “lemon” matched with an object that was presented just before the word. The researchers presented the object visually or through smell, evoking brain activity. The results demonstrated that the brain reactivated the region in the olfactory system where smells are translated into linguistic expressions, to in order to determine the meaning of the words.These findings may help explain why it is so difficult to recognize smells and  can help with the detection of early stages of dementia.
