Movie 3

Impaired arm coordination of a subject (O. incrassata) whose arms were re-anesthetized following amputation. This subject underwent anesthesia of the midsegments of its intact five arms, disabling it from coordinating arm movements for locomotion (See supplementary movie 2). The subject regained the arm movement coordination after amputating the arms proximally to the anesthetized segments (Fig. 5A, B). However, the arm movement was again discoordinated by anesthetizing the ends of the arm stubs. See text for detail.
