Fig. 4From: Prolonged morphine exposure during adolescence alters the responses of lateral paragigantocellularis neurons to naloxone in adult morphine dependent ratsAlteration of baseline firing pattern following adolescent morphine exposure. As shown, prolonged morphine exposure during adolescence has altered the distribution of baseline ISIs in neurons with excitatory (A), and inhibitory (B) responses to naloxone (the rightward shift in peak A represents more ISIs with longer durations)Back to article page
