Visualization of mimesis, an emotion-driven facial expression word, highly suggestive of laughter, heard through the ear, activates both the lingual gyms (LG) of the extrastriate cortex and the premotor (PM)/supplementary motor area(SMA) in the superior frontal gyms while non-mimic words under the same task did not activatethese areas. An fMRI-based result suggested human brain involves laughter modules both in the LG (percept of laughing face) and PM/SMA (generation of laughter). Furthermore,

... ain-implied word activated the anterior cigulate cortex (ACC) which had been reported the area related to cognitive pain. We verified the hypothesis that an activation in the ACC and LG/PM/SMA would be modulated by image formation of specific mimic word implying pain and laughter, respectively.
