Effects of indomethacin on neuronal responses after development of hyperexcitability. The recordings started 6–11 hr after induction of inflammation in the ipsilateral knee joint. Eachsymbol represents the mean ± SE of the responses of spinal cord neurons to innocuous (innoc.) and noxious (nox.) pressure onto the knee joint under spinal application and subsequent intraperitoneal administration of indomethacin.
