Figure 4
Analysis of behavior in the area directly in front of the cages with and without the stranger mouse. Each bar graph shows results from control trials on the left and from test trials (with stranger present) on the right. Bar colors correspond to genotypes (Ube3am-/p- = white bar, Ube3am-/p+ = light gray, wild-type = dark gray). (A) Time spent in front of the cage when the stranger was present (test trial) compared to the same cage when it was empty (control trial). Asterisks indicate significant differences between control and test conditions. (B) Mean number of visits to the stranger's cage during control and test conditions. Asterisks indicate a significant difference between the Ube3a deficient and the wild-type mice. Error bars are SEM.
