Last updated 2026-01-05

No results posted yet for this study

Summary

The main hypothesis of this study is that the alteration of the reward circuitry underlying the motivational deficit in chronic pain patients compared to healthy subjects results in a decrease in the capacity for reward learning. The fMRI studies have shown that this type of learning depends on the dopaminergic system innervating key regions of the reward system.
