We probed modulation of BOLD by itemwise perceptual qualities of laughter. Auditory cortices responded more to higher arousal, valence, and authenticity. Right STS was most active for items at the extremes of the authenticity scale. Anterior medial prefrontal cortex responded most strongly to low authenticity items. We suggest rSTS is sensitive to laughter salience, and amPFC to social ambiguity.
