Language, whether spoken, written, or signed, is primarily controlled by the left hemisphere. On the other hand, human communication also includes a strong nonverbal component. Clinical and experimental studies have suggested that the right hemisphere plays a dominant role in nonverbal communication. However, neural substrates related to nonverbal communication remain unclear. We measured regional cerebral blood flow using positron emission tomography (PET) to determine brain regions involved in the assessment of facial emotion. The right inferior frontal cortex showed significant activation during the assessment of facial emotion.
