In humans a substantial part of corticospinal excitation to upper limb motoneurons is mediated through cervical premotoneurons located rostral to motoneurons, analogous to the feline system of C3-C4 propriospinal neurons. The indirect (disynaptic) component of the corticospinal command passing through the propriospinal relay may be updated by the extensive convergence at this level of afferent inputs (both excitatory and inhibitory) from the moving limb. Propriospinal neurons are potently… CONTINUE READING
