Figure 4. Re-incision to neonatally-injured animals affects motivational behaviours that are driven by presence of food treats.

Figure 4

(a) Rearing behaviour decreased (F(1,56) = 34.83; p<0.001) and (b) percentage of time spent in the central zone increased (F(1,56) = 13.02); p<0.05) in neonatally incised animals with an adult re-incision (IN+IN, n = 14) versus neonatally incised alone (IN, n = 19). (c) The presence of treats affected both rearing and time spent in the central zone. When treats were absent (n = 5), animals reared more frequently (p<0.05) and (d) spent significantly less time in the central zone (p<0.01; all groups analysed via one-way ANOVA with Bonferroni's Multiple Comparison Test). *p<0.05, **p<0.01, ***p<0.001.
