  • Right arm lightly brushed


  • Surprisingly, there were activations even on the opposite to the receiving brain side
  • Detailed analysis showed activations in the pain network – bilateral insula and primary and secondary somatosensory cortices
  • Control activations were limitied to contralateral (left)¬† somatosensory cortex

Comment – there can be no doubt abnormal sensory processing is part of the disease in FM sac michael kors sac michael kors
