Rotarod measurements in male mice at different ages, expressed as the time in seconds the animal stayed in the rod. Mutant animals lacking brain AM (gray bars) are less coordinated than their wild-type littermates (open bars) at 3 months. Bars represent the mean ± standard deviation of 10 mice and 5 trials per animal. The whole experiment was repeated twice, and a representative example is presented here. **, P < 0.01; ns, no significant differences.
