Figure 4

Tail flick latencies after intra-VL PAG microinjections of vehicle (0.05% DMSO in ACSF), PGE2 (0.01, 0.1 and 1 pg) or PGE2 (1 pg) in combination with L355677 (0.1 pg). Each point represents the mean ± S.E.M of 12-14 rats per group. * indicates a statistically significant difference vs vehicle and° versus PGE2 (1 pg). P values < 0.05 were considered statistically significant.
