Withdrawal latencies following injection of DPDPE into the DLP. The details are as in Fig. 1, except that 3-day-old pups were not tested. DPDPE was less effective than DAMGO at this site. DPDPE was never fully effective at 47° C, and virtually without effect at the higher temperatures. Furthermore, it was minimally effective in the hindpaw at any temperature.
