Nathan and Smith described the Propriospinal fasciculi as Posterior or Dorsal, Lateral, and Anterior or Ventral Ground bundles (Nathan PW, Smith MC 1959 Fasciculi proprii of the spinal cord in man. Brain 82:610-668). The term Fasciculus septomarginalis (Septomarginal fasciculus) is used for: 1) the Oval bundle of Flechsig, present at lumbar levels; and 2) the Triangle of Philippe-Gombault, present at sacral levels (see Schoenen J, Grant G 2004 The spinal cord: Connections. In: Paxinos G, Mai JK, eds: The Human Nervous System, 2nd ed. Elsevier, Amsterdam, pp 236-265). The term Fasciculus interfascicularis is also known as the Comma tract of Schultze, present at cervical and high thoracic levels. According to Nathan and Smith (1959), the Comma tract consists of descending divisions of the cervical and upper thoracic dorsal roots. The Fasciculus cornucommissuralis is present throughout the cord, best developed at lumbar levels; situated along the medial side of the posterior grey column abutting the posterior commissure. It consists of ipsilaterally running propriospinal fibres (see Schoenen and Grant 2004).

For the Tractus spinoolivaris (Spino-olivary tract) as eponym Helweg tract is used. Smith and Deacon (Smith MC, Deacon P 1981 Helweg's triangular tract in man. Brain 104:249-277) denied that Helweg's tract contains spino-olivary fibres; more likely reticulospinal; Helweg's tract can be identified in Weigert-stained sections, but hardly in Luxol-Fast-Blue-stained sections. The term Fibrae olivospinales is deleted (non-existent); they are probably reticulospinal fibres; see Brodal A 1969 Neurological Anatomy in Relation to Clinical Medicine, 2nd ed. Oxford University Press, New York).
(Tractus anterolateralis): A Tract may be defined as a projection (a set of fibres with one main source and one main site of termination) which manifests itself as a fibre concentration over at least part of its course (Nieuwenhuys R 1998 Structure and organisation of fibre systems. In: Nieuwenhuys R, ten Donkelaar HJ, Nicholson C: The Central Nervous System of Vertebrates. Springer, Berlin-Heidelberg-New York, pp 113-157). For fibre systems with a more diffuse organization, the term Fibrae is advocated.
A Tractus spinohypothalamicus (Spinohypothalamic tract) has been characterized functionally in monkeys (Zhang X, Wenk HN, Gokin AP, et al. 1999 Physiological studies of spinohypothalamic tract neurons in the lumbar enlargement of monkeys. J Neurophysiol 82:1054-1058; see also Westlund KN, Willis WD Jr 2012 Pain system. IN: Mai JK, Paxinos G, eds: The Human Nervous System, 3rd ed. Elsevier, Amsterdam, pp 1144-1186).
