1902 H. Morris Treat. HumanAnat. (ed. 3) v. 769The rubro-spinal tract is formed by a number of fibres which are scattered in the anterior part of the lateral pyramid, in the posterior part of the lateral ground bundle, and in the posterior part of Lowenthal's tract.
1937 J. H. Globus Pract. Neuroanat. 150Others..descend to the brain stem and spinal cord as the rubroreticular and rubrospinal tracts.
1954 T. L. Peele Neuroanat. BasisClin. Neurol. xvii. 386/2The rubro-oculomotor fibers to the third, fourth, and sixth cranial-nerve nuclei..form the most mediodorsal part of the capsule of the red nucleus.
Ibid. 387/1Fibers to other cranial-nerve motor nuclei, a rubrobulbar tract, are probably included in the rubral outflow.
Ibid. ,Rubrofrontal and rubroparietal fibers are described as leaving the dorsolateral surface of the nucleus and passing..to frontal and parietal lobes.
1972 M. L. Barr Human Nervous System vii. 110/2Neuronal activity in the red nucleus..influences lower motor neurons through the rubrospinal tract and through rubroreticular and reticulospinal connections.
1974 D. & M. Webster Compar. Vertebr. Morphol. xii. 290The rubrospinal tract leaves the red nucleus, and the reticulospinal tract leaves the reticular formation.
