Stereotypy quantification as recorded in the activity cage in male mice at different ages. Mutant animals (f/f Cre+) present a higher number of stereotypies than wild-type littermates (wt/wt Cre+) for the first 6 months but the difference disappears in older mice. Bars represent the mean ± standard deviation of 10 mice. The whole experiment was repeated 3 times, and a representative example is presented here. *, P < 0.05; **, P < 0.01; ns, no significant differences.
