E. top: Voltage sag in response to hyperpolarizing current injection (50 pA-increments, from -400 to 0 pA) in PFC pyramidal neurons from mice injected with vehicle (Veh, n= 10 from N=5), THC (n = 11 from N=5), THC+SB258585 (THC/SB, n=7 from N=4) or THC+Rapa (THC/Rapa, n=7 from N=4) during adolescence. *** p < 0.001, one-way ANOVA followed by Bonferroni test, vs. THC-injected mice. Errors bars correspond to the mean ± SEM. Voltage sag is indicated by arrowheads.
