Suppl. Figure 2. Activity during tickling with voluntary vocalisation compared to the touch and the touch with voluntary vocalization conditions from When laughter arrests speech: fMRI-based evidence

Panel a: Brain activation during tickling with voluntary vocalization compared to monotonous foot contacts (touch). Activation of the limen (LI) part of the insular cortex, the brainstem lateral tegmental field in the area of the nucleus ambiguus (AMB), and the subcallosal area (SCA) is indicated. In the illustrated example, the level of significance for threshold activity was set at p < 0.05 (FWE corrected). Panel b: Brain activation during tickling with voluntary vocalisation compared to monotonous foot contacts (touch) with voluntary vocalisation. Activation of the posterior (PI) and limen (LI) parts of the insular cortex, of the primary sensorimotor cortex (S1/M1), the anterior cingulate cortex (ACC), the subcallosal area (SCA), and the brainstem lateral tegmental field in the area of the nucleus ambiguus (AMB) is indicated. In the illustrated example, the level of significance for threshold activity was set at p < 0.05 (FWE corrected).
