The activation threshold for the simple main effects was set at p < 0.05 FWE (family-wise error rate) for multiple comparisons using predefined ROIs for each type of joke. dlPFC = dorsolateral prefrontal cortex; vlPFC = ventrolateral PFC; vmPFC = ventromedial PFC; vACC = ventral anterior cingulate cortex.
