Activation threshold was set at p < 0.05 FWE (family-wise error rate) corrected for multiple comparisons at the peak level for the whole brain. (A) Regions activated for bridging-inference jokes but not exaggeration jokes and ambiguity jokes discovery was revealed by subtraction. (B) Brain regions commonly activated for the three types of jokes, as revealed by a conjunction analysis.
