Values represent means ± standard deviations. Three adult mice of each genotype on the C57BL6/J inbred background were analyzed. Asterisks indicate statistically significant differences (p<0.05). Abbreviations: VAP, average path velocity; VSL, straight-line velocity; VCL, curvilinear velocity; ALH, amplitude of lateral head displacement; BCF, beat-cross frequency; STR, straightness; LIN, linearity.
