Ratios of relative spike rate responses of contralateral vs. ipsilateral turn nerves to unilateral LOVN stimulation.

Dunn's Multiple Comparison Test; *p1.0. Fisher's Exact Test supports a significant effect of 5-HT in changing avoidance responses to orienting in the four experiments of Figure 3.

邓恩多重比较检验（Dunn's Multiple Comparison Test）；*p1.0。费希尔精确检验（Fisher's Exact Test）证实，在图3的四项实验中，5-羟色胺（5-HT）对定向回避反应的改变具有显著效应。
