From: Impact of enriched environment on motor performance and learning in mice
Enriched-housed animals perform better on accelerating rotarod, but not on the balance beam or grip strength tests. (A) Illustration of the balance beam test, where time crossing the beam from one side to the other was quantified on two different beam widths: 6 mm and 12 mm. (B) Boxplots of the average time (s) on the beam per group and beam width. Each dot represents a single value per mouse, with in total two values per beam width per mouse. (C) Illustration of the grip strength test, where the maximal muscle strength of the forelimbs was quantified by grabbing a bar from the grid before releasing. (D) Boxplots of the average peak strength (N) per group. Each dot represents a single value per mouse, with 8 values in total for each mouse. (E) Illustration of the accelerating rotarod, where the latency to fall was quantified. Mice had to walk on the accelerating rod (4–40 RPM) for a maximum of 300 s. (F) Line plot represent the average latency to fall (s) per trial per day, and error bars representing a 95% confidence interval. The blue data represents standard-housed mice, where the orange data represents the enriched-housed mice. *Significance level p < 0.05 after correction Bonferroni-Holm.
