FIGURE 7.

NMDA currents recorded from small neurons in the dorsal root ganglion are significantly enhanced by IL-1β. Recordings of NMDA currents evoked by NMDA (50 μm) injected onto the recorded neuron by a puff electrode at base line, during, and after washout of IL-1β are shown in A. The mean (+S.E.) amplitudes of NMDA currents at base line, during, and after washout of IL-1β are shown in bar graphs (B). The number of neurons included for the analysis is shown in each bar. **, p < 0.01; ***, p < 0.001.
