The red nuclear-thalamic tract (red nuclear-tuberous tract), the tract of the red nuclear thalamus (from the Latin tractus - “cord” and nucleus - “core”), also called the corticospinal tract, is one of the six longitudinal tracts of the midbrain connecting the cortex brain with the thalamus through the reticular formation and the pons. This tract is often referred to only as the “red nuclear pathway” or “red tuberous pathway.” The description of the path appeared thanks to the French anatomist Pierre Joseph Cabanis, who in 1841 described it for the cortical nerves that provide sensitivity to the oral cavity. Much information about the red nuclear pathway was obtained after its description by a group of British neurologists and electrophysiologists led by Maurice Sinard in 1952 and Maurice Delvet, Walter Denny
