Emotional and explorative behavioral parameters measured on days 1–10 of holeboard testing of BALB/c (white bars) and C57BL/6J mice (black bars). (A) Percentage of time spent on the centerboard, (B) number of cylinder visits, and (C) number of rearings. The gray background on day 1 indicates data during the 10 minutes exposure; data on days 2–10 present the mean values (±SEM) of three times 5 minutes exposure.^#Baited cylinders were relocated on days 9 and 10. *p < 0.05 and **p ≤ 0.001 between strains.
