Absolute mean LC spontaneous discharge and sensory evoked activity at baseline and during exposure to the social stressor (or control manipulation) in adolescent and adult animals on days 1 and 5. Animal and cell numbers for each value are provided. *p<0.05, **p<0.01, ***p<0.001; two-way rmANOVA comparison w/ controls. #p<0.05; post hoc comparison w/ day 1 values.
