Movie S1
Movements of a cockroach leg in a hybrid reflex arc. The hybrid reflex arc consists of an artificial afferent nerve and a biological efferent nerve as in Fig. 4B. Postsynaptic currents from the artificial afferent nerve were amplified and connected to a detached leg of a cockroach. When we apply a pressure onto the artificial afferent nerve, the cockroach leg was actuated. Isotonic measurements were recorded. In this case, neither the tibial extensor muscle nor the tibial flexor muscle was dissected. Thus, the movements were bidirectional. The summary plots of measurement results are shown in Fig. S21.
