Abbreviations: UMN: upper motor neurons projecting to anterior horn in spinal cord, BG: basal ganglia, stn: subthalamic nucleus, sn: substantia nigra, RN: red nucleus, IO: inferior olivary complex, mf: mossy fibers, cf: climbing fibers, Ia: spindle afferents, MNγ: gamma-motoneuron, MNα: alpha-motoneuron. MN pool: motoneuronal pool.
