(A,B) No differences were observed between non-normalized and normalized performance for body weight in balance beam walk test; (C) improvement motor swimming test at 22 and 30 weeks of age and (D) improvement at 22 weeks of in 8 and 20 rpm of Rotarod test. Bars represent the mean ± SEM (WT veh, n = 10; WT VPA, n = 15, CMVMJD135 vehicle, n = 10; CMVMJD135 VPA, n = 13), * represent p<0.05, ** represent p<0.01 and *** represent p<0.001, black asterisks represents the difference between WT and CMVMJD135, blue asterisks represents the difference between non-treated and VPA-treated CMVMJD135, (Repeated-measures ANOVA, Tukey correction for continuous variables, One-Way ANOVA for differences between groups in specific ages of the continuous variables and Mann-Whitney U test for continuous variables without normal distribution (Rotarod).
