Figure 5. Effect of repetitive tetanic stimulation on the half-width of the first tetanic peak in MT-II fibres loaded with Magfluo-4 AM.
In A the increase in the time to half-relaxation is shown (arrow) for the selected episodes (epi). Note that the recovery (recov) trace superimposes on the first trace. All traces were normalized. B is a summary of the half-width values of the first peak in fMT-II (filled squares, n = 9) and rMT-II fibres (filled circles, n = 6). *Significant differences with the first point demonstrated by a Tukey post hoc test, after a one-way ANOVA. Differences between the two curves were also found by a two-way ANOVA.
