| Outline of Final Research Achievements |
Repetitive transcranial magnetic stimulation (rTMS) is expected to relieve intractable neuropathic pain. In this research, we made chronic pain model in rats with ligated sciatic nerve, and tried to analyze detailed image to investigate the pathophysiology of chronic pain and best stimulation parameter of rTMS. We prepared anesthesia equipment, rTMS machine and electromyogram. We successfully obtained anatomical image of rat brain in 11.7T MRI according to preceded anesthesia method and MRI parameters in 7T MRI. However, our 11.7T MRI needed placement of the animal in vertical position. We cannot obtain resting-state functional MRI of rat in stable anesthesia.
