Effect of reinforcement-value. Contrast estimates (high–low) within the right anterior insula (A) and anterior cingulate cortex (B) revealed a difference between the high and low reinforcement within the reward session but no difference within the punishment session. Activations are superimposed on the mean of the individual subject T1 images at p < 0.001 (uncorr., k > 110 voxels). Note that the extraction of contrast estimates is only illustrative and inferences were made from the original analysis.
