When words associated with a strong smell were presented (such as perfume), the primary olfactory cortex was activated.
Stories activate more regions of the brain than language alone. In a 2006 Study conducted in Spain, researchers had participants read words while having their brains scanned by an MRI machine. When words associated with a strong smell were presented (such as perfume), the primary olfactory cortex was activated. These regions of the brain were not active when the word did not have these associations (such as chair).
