We reasoned that other motor coordination assays, like the elevated beam in which mice can slip multiple times during the completion of the task, might provide a more nuanced readout of motor deficits, as has been observed in some animal models of ataxia (Larivière et al., 2015), although there are animal models, like the SCA3 transgenic mouse, where deficits are detected with rotarod before elevated beam (Switonski et al., 2015). Here, ATXN3 is linked to Ataxia.
