Note. Means and SEM for locomotor activity across 30 minutes. Distances are measured in cm, time in seconds, and movements/beam interruptions are measured in counts. Bold indicates a main effect of adolescent footshock,

indicates a main effect of sex, and letters indicate a significant overall interaction, with individual letters indicating groups that are statistically different (i.e., different letters = statistical difference).
