A-D. Mice were injected daily with THC (5 mg/kg) or vehicle (Veh) during adolescence, from PND 30 to 45. SB258585 (SB, 2.5 mg/kg) or rapamycin (Rapa, 1.5 mg/kg) were administered concomitantly with THC (n=20 from N=5) or vehicle (n=18 from N=6). Electrophysiological recordings were performed from PND 60. B. Action potentials were evoked by a ramp current injection with a 10 pA-step for 2 ms and only the first action potential (AP) were used to estimate the AP threshold: -34.1 ± 0.7 mV and -39.7 ± 0.8 mV for Vehicle- and THC-injected mice, respectively, p < 0.001.
