Figure 4

The assessment of toxicity of ZnCl₂ exposure on learning and memory performances in the T-maze test. (A) The latency (s) of control and ZnCl₂-incubated fish to swim into the punishment chamber for each training session. (B) The time spent in the punishment chamber (s) of control and ZnCl₂-incubated fish at different time points (before and after training). (C) The freezing time (s) of control and ZnCl₂-incubated fish at different time points before and after training. (D) The total number of electric shocks given for control and ZnCl₂-incubated fish. (E) The memory retention latency (s) of control and ZnCl₂-incubated fish at different time points after training. (F) The typical swim locomotion trajectories for control fish before (left panel) and after training (middle panel), and for ZnCl₂ exposed fish after training (right panel). The data are expressed as means ± SEM. The data were analyzed by two-way ANOVA and followed with the Tukey–HSD test (** p < 0.01, n = 18). Different letters (a, b, c) on the error bars represent significant differences (p < 0.05).
