DAMGO concentration-response relationships of DRG neurons from rats with freely perfused (▲) and 72 h-ligated (•) femoral arteries (see Fig. 6 legend for details). Each data point represents the mean (±SE) prepulse Ca²⁺ current inhibition; the numbers in parentheses indicate the number of neurons that was tested. The smooth curves were obtained by fitting the data points to the Hill equation, and the calculated IC₅₀ values are shown in the figure key.
