Figure 2.

The development of disability in TMEV infected SJL/J mice vs controls. Y axis: rotarod scores (sec), X axis: time (months); blue: cases; pink: controls. Note that the controls continue to demonstrate signs of motor learning for the first 6 months, after which their performance reaches a plateau. In sharp contrast, TMEV infected mice show a consistent drop in motor performance that first reaches significance at the 4 months time point.
