Movie 1.

Video sequences for controls, autotomy treatments and trials with regenerated legs. This video compilation features: 1) sample videos for the C1 intact controls, a 1AUTO treatment (day of first two-leg autotomy treatment) and C2 (after leg regeneration); 2) Simulated videos illustrate the various model gaits hypothesized for these various treatments; 3) example videos that show the actual leg motions used by spiders with 8 legs (intact) and after two-leg autotomy, annotated to show the gait clusters used and the legs in stance in each frame.
