Summary of intersegmental feedback network in motor circuits. a Model of the roles of intersegmental feedback neurons Ifb-Fwd (left) and Ifb-Bwd (right) in transforming the progression of a wave front to the intersegmental delay in forward (left) and backward (right) propagations, respectively. b Schematic of connectivity from intersegmental feedback neurons (Ifb-Fwd and Ifb-Bwd) through the shared module (A02e and A03g, as examples) to MN synergy (longitudinal MNs and transverse MNs) in the nerve cord. Ifb neurons and the shared neurons form synaptic contacts at a centrolateral region of the neuropil (arrowhead). c Schematic of functional domains within the neuropil. Intersegmental feedback signals are conveyed at the centrolateral regions (arrowheads)
