(a) Significant higher functional activity in the amygdala in the funny vs. typical condition, the error bars represent SEM. (b) Higher amygdala activity was associated with increased generation of funny idea. (c) Reduced functional connectivity between the amygdala and the superior/medial frontal gyrus was associated with increased funny idea generation (d) A higher negative functional connectivity between the amygdala–superior/medial frontal gyrus was associated with an increased functional activity in the amygdala.
