Altered neural oscillations in chronic jaw pain


  • Individuals who experience chronic pain have attenuated rather than magnified neural responses to heat stimuli in the context of system-level changes in intrinsic sensorimotor and attentional circuits.

Why this matters

  • In healthy adults, pain perception is associated with motor system priming and orienting of attention, leading to processes that decrease in alpha and beta power in both the sensorimotor and parietal cortices, however, it is unknown if these findings extend to individuals with chronic pain.

  • Examining the neural oscillation within and between sensorimotor and parietal cortices in chronic jaw pain reveal alterations that reflect a relative increase in inhibition in sensorimotor and attentional networks.
