Behavioral effects of 3 days exposure to 0.75 mM acrylamide (ACR) on zebrafish: erratic movements and freezing bouts. Erratic movements, number and duration (s) of freezing bouts manual and ethograms allowing to visualize the occurrence of these behaviors and the transitions between them, with the diameter of each circle reflecting the frequency of the behavioral activity, and the width and direction of each arrow representing the frequency of the transitions between behaviors. Data reported as mean ± SEM (n = 23–24), *p < 0.05, **p < 0.01, ***p < 0.001 (Student’s t-test). Data from 3 independent experiments.
