| Research Abstract |
In neuropathic pain and inflammatory pain, enhanced efficacy of synaptic transmission in the dorsal horn of the spinal cord underlies central major aspects of hyperalgesia and tactile allodynia. Moreover, patients with chronic pain frequently have been demonstrated to express various symptoms of neuropsychologic impairment, including chronic fatigue, depression, anxiety, sleep disturbance and cognitive deficits, suggesting that synaptic transmission is also altered at the supraspinal areas. Thus, behavioral studies as well as electrophysiological studies were made to explore pathophysiology of neuropathic pain and the effects of some potentially analgesic drugs, which we consider is important to obtain crucial information for developing novel analgesic drugs to treat chronic pain.
