In Brief In considering the role of common synaptic input to motor neurons in force control, we hypothesize that the effective neural drive to muscle replicates the common input and is, thus, the main determinant of force production. Such a perspective argues against a significant role for motor unit synchronization in force control. We describe the fundamental role that common synaptic input to motor neurons has in the control of muscle force.
