Graphs illustrating the effects of open-field exposure in low-light (LL: 8-13 lux) or high-light (HL: 400-500 lux) conditions on behavior in Experiment 1 (CO, n = 9; LL, n = 9; HL, n = 9). Graphs illustrate A) locomotor activity, scored as the number of square entries during each five min block of the 15 min open-field test (mean + SEM); *p < 0.05 versus LL within each time block; post hoc Bonferroni comparisons, +p < 0.05, versus 0-5 min time block within each light condition; post hoc Bonferroni pairwise comparisons, B) time spent in the outer section of the open-field, and C) time spent in the center of the open-field, *P < 0.05 versus LL group; independent samples t-tests.
