Fig. 2 Fig. 2. Increased dopaminergic activity in the anterior brain region of zebrafish exposed to 0.3 and 3 μg/L glyphosate for 2 weeks. Levels of L-tyrosine, DOPAC, HVA, and the ratios DOPAC/DA and HVA/DA increased significantly in the anterior brain of zebrafish exposed to 3 μg/L glyphosate for 2 weeks. The cartoon on the upper left shows a dorsal view of an adult zebrafish brain, with the three regions collected for the neurotransmitter analysis. Data reported as scatter plot with the median. *P < 0.05, **P < 0.01, ***P < 0.001; one-way ANOVA with Dunnett’s multiple comparison test (NE) or Kruskal Wallis test with Bonferroni correction (L-tyrosine, DA, DOPAC, HVA, 3-MT, DOPAC/ DA, HVA/ DA). Data from 2 independent experiments.
