| Outline of Final Research Achievements |
Little is known about the role of glycineergic neuron of spinal dorsal horn in neuropathic pain. We analyzed changes of inhibitory neuronal transmission between normal rats and neuropathic pain model rats using in vivo patch-clamp technique. As a result, only the amplitude of the inhibitory postsynaptic current decreased. There was no difference in the frequency and amplitude of glycineergic IPSC between the two groups. Furthermore, in model rats relative GABAergic neurons increased. The balance changes of these inhibitory neurons were thought to play a part of plasticity change in neuropathic pain.
