Cortical … WebLithwick (2013) observed that in individuals with chronic back pain, m PFC was in a significant hyperactive state, which may reduce brain activity in other areas overall, affecting the brain’s ability to perform other tasks. [2] Overall, the change in PFC due to chronic pain represents a shift towards increased emotional processing.
