The C3-C4 propriospinal system in the cat and monkey: a spinal pre-motoneuronal centre for voluntary motor control.

This review deals with a spinal interneuronal system, denoted the C3-C4 propriospinal system, which is unique in the sense that it so far represents the only spinal interneuronal system for which it has been possible to demonstrate a command mediating role for voluntary movements. The C3-C4 propriospinal neurones govern target reaching and can update the descending cortical command when a fast correction is required of the movement trajectory and also integrate signals generated from the forelimb to control deceleration and termination of reaching.
