Fig. 9. Behavioral analysis of wild-type (bl6), blind wild-type (bl6b) and ak mice. (A) Level of climbing behavior (n=10, all males). The y-axis represents the average score of 10 animals in each group. The error bars indicate the standard error of the mean within the groups. The groups were significantly different from each other (Krukal-Wallis test, P<0.01). Wild-type mice/blind mice (P<0.01); wild-type mice/ak (P<0.01); blind mice/ak (P=0.124). B) Horizontal movement in an open field. Movement was recorded by automatic analysis software (Ethovision). All groups were significantly different from each other (One-way ANOVA P<0.01), as well as within groups (P<0.01, for all combinations).
