Table 3. Statistical summary for linear models assessing how percent relaxation changes over each successive twitch in stimulation trains of different frequencies.
After evaluating whether each species’ SH exhibited a change in performance with repeated stimulations, we also compared the two slope estimates with an F-test. All p-values reported have been adjusted to control for the false discovery rate.
