(A) Control group rats. No abnormal neurobehavior was detected in the controls. (B)–(E) Representative images of abnormal neurobehavior in bilirubin-treated rats. Almost all of the bilirubin-treated pups showed clenched fists (B–C) (black arrow) and opisthotonos (D); some rats showed the latericumbent position (E). (F) Comparison of prostration in the two groups. The bilirubin-treated rats show decreased muscular tone (black arrow) and prostration.
