Connections of the superior colliculus to shoulder muscles of the rat: a dual tracing study.
TL;DR: The results demonstrate that the connection of the SC to the skeletal muscles of the forelimb is at least trisynaptic, and suggest this projection to be involved in more global functions in motivated behavior like general arousal allowing fast voluntary motor activity.
Pyramidal actions in identified radial motornuclei of the cat.
Michael Illert,Ernst Wiedemann +1 more
TL;DR: It is concluded that disynaptic corticospinal excitation of distal DR motornuclei is relayed in a short midcervical propriospinal system, which allows the brain to adapt the reflex mechanisms of the distal forelimb to the synergistic-antagonistic relations between the muscles, which are changing according to the performed movement.

Monosynaptic rubrospinal projections to distal forelimb motoneurons in the cat.
Yutaka Fujito,Mamoru Aoki +1 more
TL;DR: The present results suggest the presence of preferential direct rubrospinal projection to Mns innervating distal forelimb muscles in the cat, and rubromotoneuronal connections are, at least in part, monosynaptic forforelimb Mns that innervate in particular the hand and digit muscles.

Enhanced propriospinal excitation from hand muscles to wrist flexors during reach-to-grasp in humans.
TL;DR: It is concluded that the feedforward activation of propriospinal neurons and their feedback control may be involved in the internal model, motor planning, and online adjustments for reach-to-grasp movements in humans.

Corticospinal vs Rubrospinal Revisited: An Evolutionary Perspective for Sensorimotor Integration.
Rafael Olivares-Moreno,Paola Rodriguez-Moreno,Veronica Lopez-Virgen,Martín Macías,Moisés Altamira-Camacho,Gerardo Rojas-Piloni +5 more
TL;DR: In this article, anatomical, neurophysiological, and behavioral evidence suggest that both systems modulate complex segmental neuronal networks in a parallel way, which is important for sensorimotor integration at spinal cord level.

A cytoarchitectonic atlas of the spinal cord in the cat.
TL;DR: An atlas of the eat’s spinal cord may be of some practical importance as a guide in physiological research on the cord and the cytological and cytoarchitectonic description of the normal cord must serve as a basis of future synaptological and functional interpretation of its structure.

An inhibitory mechanism in the bulbar reticular formation
H. W. Magoun,R. Rhines +1 more
TL;DR: In the experiments to be reported, this inhibitory influence has been demonstrated by observing the effect of bulbar stimulation upon reflexes, upon decerebrate rigidity and upon responses evoked from the motor cortex.

The descending pathways to the spinal cord, their anatomy and function.
TL;DR: This chapter discusses the descending pathways to the spinal cord, which appeared to be directed to the cervical segments, as only few fibers were found in the lumbo-sacral segments despite the damage to the rubro spinal tract.
