Figure 4.

(A) Brain responses associated with effect of the painful priming selectively for high consistency trials (contrast: (PNhigh > NThigh) > (PNlow > NTlow)), and parameter estimates extracted from the cluster in the anterior prefrontal cortex (PFC). (B) Effect of the pleasant priming selectively for high consistency trials (contrast: (PLhigh > NThigh) > (PLlow > NTlow)) and parameter estimates extracted from the cluster in the left sensorimotor cortex. None of the contrasts investigating the priming effect in the “low consistency” trials over the “high consistence” ones showed significant clusters in the group analyses. P < 0.05 (FWE) at cluster level; cluster size k > 300 voxels. Note: aPFC= anterior prefrontal cortex; SM1= primary sensorimotor cortex. [Color figure can be viewed at http://wileyonlinelibrary.com]
