Cycle periods and burst durations in hindlimb kicking motor patterns <i>in vitro</i>.

UL performed either pre- or post-metamorphosis caused no significant changes in the fictive locomotor cycle period, whereas the durations of extensor bursts were significantly altered following a post-metamorphic UL. Note also a slight increase in ipsilesional flexor burst durations in UL66 juveniles compared to both intact and UL54 animals. The number of animals in each group is indicated in brackets and the power of non-significant ANOVA tests in parentheses.
