a–d Ts65Dn mice were not significantly impaired on rotarod performance, as measured by latency to fall from the accelerating rotarod, when compared to WT controls (Cohort 1: F1,1 = 0.0037, NS; Cohort 2: F1,1 = 1.57, NS). a Cohort 1 WT displayed similar motor learning curves when trained with massed versus spaced trials (F1,22 = 0.336, NS). WT showed a significant effect of training day (F2,44 = 45.8, p < 0.0001), and a significant interaction between massed versus spaced x training day (F2,44 = 6.03, p < 0.01). b Cohort 1 Ts65Dn displayed similar motor learning curves when trained with massed versus spaced trials (F1,22 = 0.05, NS). Ts65Dn showed a significant effect of training day (F2,44 = 23.2, p < 0.001), but no interaction between massed versus spaced x training day (F2,44 = 0.613, NS). c Cohort 2 WT displayed similar motor learning curves when trained with massed versus spaced trials (F1,23 = 0.112, NS). WT showed a significant effect of training day (F2,46 = 15.6, p < 0.001), but no interaction between massed versus spaced x training day (F2,46 = 2.24, NS). d Cohort 2 Ts65Dn displayed similar motor learning curves when trained with massed versus spaced trials (F1,24 = 2.30, NS). Ts65Dn showed a significant effect of training day (F2,48 = 84.1, p < 0.001), but no interaction between massed versus spaced x training day (F2,48 = 0.116, NS). e–f
Ube3a mice were significantly impaired on rotarod motor learning as compared to WT controls (F1,1 = 118.6, p < 0.001). e WT displayed similar motor learning curves when trained with massed versus spaced trials (F1,22 = 0.044, NS). WT showed a significant effect of training day (F2,44 = 25.2, p < 0.001), but no interaction between massed versus spaced x training day (F2,44 = 1.02, NS). f
Ube3a displayed similar motor learning curves when trained with massed versus spaced trials (F1,22 = 1.47, NS). Ube3a showed a significant effect of training day (F2,44 = 11.8, p < 0.001), but no interaction between massed versus spaced x training day (F2,44 = 0.0874, NS)
