| Outline of Final Research Achievements |
We made patch-clamp recordings from substantia gelatinosa neurons in the adult rat spinal dorsal horn in vivo or in spinal cord slices. We revealed that intrathecal administration of Ultiva (remifentanil); to SG neurons hyperpolarized membrane potentials and depressed presynaptic glutamate release predominantly through the activation of glycine receptors. We also found that Ketamine increased presynaptic glutamate release. This result raises the possibility that Ketamine has pronociceptive effect in the spinal cord.
