Figure 5.
Effect of co-exposure to developmental MeHg + SeMet on adult expression of visual responses to a rotating black bar under low light conditions. A range of 0.0-0.30 μM SeMet was used as a co-exposure with either 0.03 or 0.10 μM MeHg as indicated by the dashed lines above the bars. Dotted horizontal line represents the expected number of responses if the fish reacted once each time the black bar completed a circuit around the glass holding dish, i.e., 10 revolutions/minute for 5 minutes = 50 responses. Bars with different letters are statistically different (ANOVA, P< 0.05, Tukey’s HSD Test, P < 0.05).
