(Top) Gelotophobics exhibited positive functional connectivity between the left caudate (seed) and the left dorsolateral prefrontal cortex (dlPFC), and negative connectivity between the right insula and right ventromedial PFC (vmPFC) for hostile jokes versus non-hostile jokes. (Bottom) Non-gelotophobics showed positive functional connectivity between the right amygdala (seed) and the right insula and positive functional connectivity between the right ventral anterior cingulate cortex (vACC) (seed) and the left midbrain and left orbitofrontal cortex (OFC). The red regions represent the seeds including the caudate, amygdala, and vACC. A red line represents a positive interaction, whereas a blue line represents a negative interaction.
