Neuroimaging studies using fMRI, functional magnetic resonance imaging, show us that when we seem someone yawn or even hear their yawn, a specific area of the brain housing these mirror neurons tends to light up, which, in turn, causes us to respond with the same action: a yawn!
Neurosnimanje koristeći fMRI, funkcionalno snimanje magnetskom rezonancom, pokazuje da kada vidimo nekog da zijeva ili čujemo njihovo zijevanje, posebno područje mozga koje sadrži te zrcalne neurone se aktivira, što, zauzvrat, čini da odgovorimo istom akcijom: zijevanjem.
