Manifest YAC128 mice: performance and striatal activity during rotarod. (A) Latency to fall over days of training for manifest YAC128 compared with WT (genotype, P < 0.0001; time, P < 0.0001; multiple comparisons: day 1, P = 0.0072, denoted by **; day 2, P < 0.0001, denoted by ****; day 3, P = 0.0001, denoted by ***; day 4, P < 0.0001, denoted by ****). (B) Percentage of trials where mice fell, rotated, or completed the full duration. (C) Paw slips during the first 10 seconds for WT and manifest YAC128 over days of training (genotype, P < 0.0001; day, P = 0.0021; multiple comparisons: day 1, P = 0.0335, denoted by *, day 2, P = 0.0034, denoted by **). (D) Right and left paw heights over days of training (genotype, P < 0.0001 both paws; day: right paw, P = 0.0035; left paw, P < 0.0001; multiple comparisons day 1: right, P = 0.0118, denoted by *, left, P = 0.0271, denoted by *; day 3: right, P = 0.0486, denoted by *). (E) SD of right and left paw height (genotype, P < 0.0001 both paws; day: right paw, P = 0.0104, left paw, P = 0.0128; multiple comparisons day 1: right, P = 0.0194, denoted by *, left, P = 0.0001, denoted by ***; day 2: right, P = 0.0034, denoted by **, left, P = 0.0255, denoted by *; day 3: right, P = 0.0342, denoted by *, left, P = 0.0028, denoted by **; day 4: left, P = 0.0233, denoted by *). (F) Latency to fall for WT, and YAC128 GP and PP (group, P < 0.0001; day, P < 0.0001; interaction, P = 0.0030). (G) Left: Mean z score on rotarod over days of training in WT and GP YAC128 (genotype, P = 0.0079; day, P < 0.0001). Right: Examples from one WT and one GP YAC128 showing jGCaMP7f traces (three trials averaged) on day 1 (top) and day 4 (bottom). Gray areas denote approximate times when mice are on the rotarod based on daily mean latency to fall (YAC128, dark gray; WT, light gray). Dotted lines indicate mean latency to fall of the three trials (YAC128, red; WT, black). GP, good performers; PP, poor performers; SD, standard deviation; WT, wild type; YAC128, yeast artificial chromsome‐128CAG. [Color figure can be viewed at wileyonlinelibrary.com]
