Vogel conflict test. Effects of LY235959 (4 nmol/200 nL), Nω-propyl-L-arginine (0.04 nmol/200 nL) and c-PTIO (1 nmol/200 nL) injected into the dlPAG of rats submitted to the Vogel test. Bars represent the mean ± SEM total number of punished licks in the 3 min session. Animals that received drugs outside the dlPAG were included as OUT groups. Asterisk indicates significant difference from vehicle (P < 0.05, ANOVA followed by the Dunnet's test; vehicle (veh, n = 10), LY235959 (n = 8), Nω-propyl-L-arginine (n = 7), c-PTIO (n = 9); OUT-LY235959 (n = 11), OUT-Nω-propyl-L-arginine (n = 5) and OUT-c-PTIO (n = 8).
