Fig. 4. Summary of movement times (mean + 1 s.d.) of crayfish to and through the junction of the maze, (A) after antennae midpoint or base ablation (experiment 1); (B) before and after ablation of one antenna (experiment 2); (C) after chelae ablation (experiment 4). No differences were detected between the treatments in the three experiments (time to junction Exp. 1: T₍₂₄₎=0.94, P=0.349; Exp. 2: P>0.05 for all ANOVA terms; Exp. 4: F_(2,101)=1.27, P=0.286; time in junction Exp. 1: T₍₂₄₎=1.08, P=0.284; Exp. 2: P>0.05 for all ANOVA terms; Exp. 4: F_(2,101)=0.67, P=0.515).
