Swimming in X. laevis tapoles and the swim CPG. Both interneurons and motor neurons participate in this motor pattern. Rohon-beard sensory neurons, stimulated by touch, activate excitatory dla and dlc neurons, which in turn, stimulate dINs to control the rhythmic output of the motor neurons (MNs). Commisural cIN interneurons coordinate unilateral flexion through contralateral inhibition. Inhibitory aINs regulate high frequency swimming and inhibit sensory activation (modified from [47, 53]).
