Visual cliff test reveals perturbed depth perception in Asah1^P361R/P361R mice. A and B: Representative movement traces of 8- to 9-week–old Asah1^+/+ (A) and Asah1^P361R/P361R (B) mice during the visual cliff test. Distance traveled in each zone expressed as ground/air ratio. C:Asah1^P361R/P361R mice spend equal amounts of time in both the ground side and the air side. D: Duration spent in each zone expressed as ground/air ratio. E and F: Percentage of the distance traveled (E) and the time spent (F) on the ground side. Data are expressed as means ± SEM. n = 15 animals for each genotype. ^∗∗∗P < 0.001.
