  1. The symbol ‘>’ denotes that the amplitudes associated with the stimuli or brain areas on the left side of the ‘>’ symbol are significantly greater than those on the right side, and that no significant difference exists among the stimuli or brain areas on the same side of the ‘>’ symbol for each case. Note that nonsignificant 2-way interactions between every two factors are not shown for a better demonstration. The degrees of freedom are shown after each factor.
  2. F is the F-value from ANOVA, ε the values of epsilon of Greenhouse-Geisser correction, LSD least-significant difference test, LT and RT the left and right telencephalon, LD and RD the left and right diencephalon, LM and RM the left and right mesencephalon, ND the call of N. daunchina, NH the call of N. hainanensis, NO the call of N. okinavana, NA the call of N. adenopleura, NL the call of N. lini, N/A not applicable.
  3. *p < 0.05, **p < 0.001.
