The view of the role of motor neurons could be changing, thanks to new research. Motor neurons, which extend from the spinal cord to muscles and other organs, have always been considered passive recipients of signals from interneuronal circuits. Now, however, researchers have demonstrated a new, direct signalling pathway through which motor neurons influence the locomotor circuits that generate rhythmic movements.
