a Representative short-latency C-bend (SLC) and long-latency C-bend (LLC) startle response of a control zebrafish larva at 6 dpf in comparison to a typical response of a PCB153 treated larva. b Vibro-acoustic startle latency at highest stimulus intensity (43 dB) in vehicle control (n = 448), NDL PCB153 1000 nM (n = 115), NDL PCB153 100 nM (n = 226), NDL PCB153 30 nM (n = 117), NDL PCB153 10 nM (n = 112), NDL PCB138 (n = 68), NDL PCB118 (n = 99), NDL PCB52 (n = 97), and DL PCB126 (n = 86) exposed larvae. c Bias of SLC and LLC and d response rate of different exposure groups at different vibro-acoustic intensities. All data points are biologically independent samples from at least three independent experiments and mean ± SEM shown in the plots of (c, d). Binomial GLM was used for statistical analysis in (c, d). Significant differences to DMSO controls (p < 0.01) are indicated by open symbols.
