Cerebellum-dependent motor memory consolidation deficits in Kdm3b+/− mice. a Experimental scheme. Eye movement was measured every 10 min in the training session, and after the consolidation session (upside-down triangles). b Representative optokinetic response (OKR) of Kdm3b+/+ (blue) and Kdm3b+/− (red) mice evoked by screen oscillation (black) before and after training. c Changes in OKR gains of Kdm3b+/+ (n = 14 mice) and Kdm3b+/− (n = 14 mice) groups in the training session. d Comparison of OKR gains in Kdm3b+/+ and Kdm3b+/− mice before and after the consolidation sessions. A two-way repeated-measures ANOVA post-hoc Tukey test was used to test statistical significance between two groups. ** and n.s indicate p < 0.01 and p > 0.05, respectively.
