Fig. 3 Fig. 3. Sertraline effects on the anxiety-like behavior and locomotor behavior of zebrafish larvae after 6 d exposure over 60 min in the dark-light preference assay (mean ± SEM). (A) Group mean of the cumulative duration per minute in dark zone per intervals; (B) Cumulative duration (s) of larval zebrafish in dark zone per 15 min intervals; (C) Group mean of the frequency of visiting the dark zone per minute intervals; (D) Frequency of visitation in the dark zone per 15 min intervals. (E) Total distance moved (mm) in whole arena, dark zone and light zone over 1 h; (F) Mean velocity (mm/s) in whole arena, dark zone or light zone over 1 h. Bars with different letters denote significant differences from each other (One-way ANOVA followed by Holm-Sidak's multiple comparisons test; n = 24; p < 0.05).
