We found that having control over pain makes expectations more precise, and changes pain perception. This is accompanied by activation changes in the PAG, SMA and ACC.

Many things are annoying about the typical peer review process. But sometimes, you are fortunate to review a great paper with a clear rationale and methods, and it inspires you to think about the implications for your own work. The signal, in a sea of noise.
