Means (+ SEM) for behavioral parameters over weeks of task performance. A) Task duration and B) Reach rate after 1 (baseline), 6 and 12 weeks of MRHF task performance. C) Cutaneous sensitivity (withdrawal threshold) and D) grip strength are shown for controls (C) and after 6 and 12 weeks of task performance. Significant declines from week 1 or control levels are denoted by symbols (*p<0.01, **p<0.001). The number of animals quantified per group: controls (n=39), week 1 (n=11), week 6 (n=17) and week 12 (n=13).
