Swimming ability improves over a period of eight weeks after a complete spinal cord transection in adult zebrafish.

<p>(A) Examples of swimming path recorded in a five-min period at two- (“2 wpl”) and eight (“8 wpl”) weeks post-lesion. (B) Boxplot diagram demonstrating the median distance swam and confidence interval of the median during the five-min period. Asterisks indicate significant differences between groups (Kruskal-Wallis test, followed by Mann-Whitney U test with Bonferroni correction, p significant if ≤0.003). Two weeks post-lesion group is significantly different from all other groups. Normal (unlesioned) group is significantly different from all other groups. (C) A cumulative distribution plot illustrating the differences in the distribution of data between individual groups. (unlesioned (n = 19), sham-injured (n = 20), 2 wpl (n = 20), 4 wpl (n = 33), 6 wpl (n = 34), 8 wpl (n = 35).
