  • Adult Ctcf CKO mice have impaired balance and fine motor coordination in tests of sensorimotor function. Behavioral performance of the adult (3–4 months old) Ctcf CKO (n = 9) and control (n = 10) mice was evaluated on the battery of sensorimotor tests. The first column lists the behavioral test conducted. The second and third columns list the means ± SEM for controls and Ctcf CKO mice, respectively. The fourth column lists the p-value obtained for Student's t test using t(17) degrees of freedom (df). The last column indicates the degree of statistical significance. Time to fall from a mesh screen oriented at 60°, 90°, and 180° (inverted) was similar between Ctcf CKO and control mice. Animals of both genotypes had similar latency to initiate walking. Ctcf CKO mice had difficulty with: balancing on a narrow ledge (t(17) *p = 0.010); balancing on a small, circular, elevated platform (t(17) **p = 0.001), and climbing down an elevated pole (t(17) *p = 0.038).
