Effect of 20E on locomotion behavior. Effect of 20E on locomotion behavior. (A) Variation in relative changes in total distance walked and instantaneous velocity for sham controls (white circles) and 20E-injected (black squares) crayfish. Abscissa represents time in days after injection (0 is immediately before injection). Injection is represented by black arrows. (B) Distribution (%) of instantaneous velocity for 20E-injected crayfish before treatment (white bars, left) and 5 days after treatment (dark bars, right). Gray lines represent distribution medians.
