Fig. 3From: Prolonged morphine exposure during adolescence alters the responses of lateral paragigantocellularis neurons to naloxone in adult morphine dependent ratsBaseline activity, coefficient of variation and distribution of responses to naloxone. The effect of adolescent morphine exposure on spontaneous firing rate (A for excitatory and inhibitory responses: n = 26 and 8, respectively). The effect of adolescent morphine exposure on CV of ISIs (B for excitatory and inhibitory responses: n = 26 and 8, respectively). The effect of adolescent morphine exposure on distribution of response types (C for excitatory and inhibitory responses: n = 26 and 8, respectively). *P < 0.05 vs. Sal–Mor group, Sal saline, Mor morphine.
