Closer analysis of the rotarod performance over the 3 days
indicates that most of the genotype difference in learning occurred
between day 1 and day 2. Specifically, wt and rd1 mice increased their
latency by 788% and 740% respectively. In contrast ak mice only
improved their performance by 57% from day 1 to day 2 which was
significantly lower than wt (pb0.05) and rd1 (pb0.05) groups
(Kruskall–Wallis test). From day 2 to day 3 wt, rd1 and ak mice
showed only slight improvement of 41%, 90% and 22% respectively
which is markedly reduced compared to the improvement observed
from day 1 to day 2.
