Synaptic input to motoneurons was traditionally thought to flow passively from the dendrites to the soma and initial axon segment. It is now clear that voltage-sensitive channels in motoneuron dendrites can generate large active currents, which are influenced by neuromodulators that are released by brainstem neurons. These neuromodulators may be essential for generating large forces.
