Figure 4. Group differences for the non-hostile jokes.
Non-gelotophobics showed greater activation than gelotophobics in the bilateral insula, bilateral ventromedial prefrontal cortex (vmPFC), right midbrain (substantia nigra, SN), and left ventral anterior cingulate cortex (vACC). The solid lines represent the evoked hemodynamic responses. The dotted lines represent the 95% confidence interval (95% CI) for the entire curve. All figures are displayed in neurological convention. L = left; R = right.
