Chapter 7 – Pharmacological fMRI 241 Figure 4. Results of the fMRI analysis. Differences in BOLD activations between baseline pain and nocebo-augmented increased pain responses were found in the operculum (A). Contrasting nocebo and control trials resulted in differential BOLD activations during nocebo acquisition (B), evocation (first 10 extinction trials; C), and extinction (last 18 extinction trials; D). Parameter estimates are plotted for all clusters and contrasts (E). Brain images are in neurological display convention.
