Summary

Chronic pain, like low back pain, expands brain maps in the primary somatosensory cortex, creating a "pain memory." This reorganization is also seen in phantom limb pain and can be influenced by various treatments.

Area of Science:

  • Neuroscience
  • Pain Research
  • Somatosensory Cortex

Context:

  • Chronic low back pain exhibits an expanded representation in the primary somatosensory cortex that correlates with pain duration.
  • Phantom limb pain involves reorganization of functional brain maps in the primary somatosensory cortex, with magnitude linked to reorganization extent.
  • This cortical reorganization is absent in congenital amputees or those without phantom limb pain.

Purpose:

  • To explore the role of

Summary:

  • Stimulation in painful areas of patients with chronic low back pain reveals an expanded representation in the primary somatosensory cortex, which grows with chronicity, suggesting a
