For the Nucleus cuneatus (Cuneate nucleus), the new subdivision into 4 parts by Florence SL, Wall JT, Kaas JH (1989 Somatotopic organization of inputs from the hand to the spinal gray and cuneate nucleus of monkeys. J Comp Neurol 286:48-70) is used, as in Paxinos G, Huang X-F (1995 Atlas of the Human Brainstem. Academic Press, San Diego).

The Nucleus paramedianus posterior is also known as the Nucleus of the anterior funiculus, and possibly, is a precerebellar nucleus (Baizer JS, Baker JF, Haas K, Lima R 2007 Neurochemical organization of the nucleus paramedianus dorsalis in the human. Brain Res 1176:45-52; Olszewski and Baxter3, page 281).

It should be noted that the Inferior and Superior salivatory nuclei appear to be a distributed set of neurons that do not condense into nuclei as such (Blessing WB 2004 Lower brain stem regulation of visceral, cardiovascular, and respiratory function. In: Paxinos G, Mai JK, eds: The Human Nervous System, 2nd ed. Elsevier, Amsterdam. pp 465-478).

The Zona reticularis intermedia (Intermediate reticular zone of Paxinos et al. 1990) is the junctional zone between the alar and basal plates in the medulla oblongata and retropontine tegmentum. It contains the motoneurons of the ambiguus, retrofacial and facial nuclei, and the retroambiguus nucleus (Paxinos G, Huang X-F 1995 Atlas of the Human Brain Stem. Academic Press, CA). The IRZ around this motoneuron column includes the Bötzinger complex, the pre-Bötzinger complex and rostral and ventral respiratory and vasomotor groups (Blessing WW, Benarroch EE 2012 Lower brainstem regulation of visceral, cardiovascular, and respiratory function. In: Mai JK, Paxinos G, eds: The Human Central Nervous System, 3rd ed. Elsevier, Amsterdam, pp 1058-1073). Alternatively, certain nuclei have been grouped as Lateral reticular formation (Nieuwenhuys R, Voogd J, van Huijzen C 2008 The Human Central Nervous System, 4th ed. Springer, Heidelberg).

The Nucleus externus is a laminar structure; in Amunts K, Morosan P, Hilbig H, Zilles K (2012 Auditory system. In: Mai JK, Paxinos G, eds: The Human Nervous System, 3rd ed. Elsevier, Amsterdam, pp 1270-1300) described as External cortex of Inferior colliculus (ECIC) to replace the TA term Nucleus lateralis. In TH, the Nucleus pericentralis is described as Dorsal cortex with Layers I-IV, based on: Geniec P, Morest DK (1971) The neuronal architecture of the human posterior colliculus; Acta Oto-Laryngol 295:(Suppl):1-33; supported by immunohistochemical data in rhesus monkeys by Amunts et al. (2012; their Dorsal cortex of inferior colliculus).

The Nucleus striae terminalis (Bed nucleus of the stria terminalis) can be subdivided into various subnuclei, the best known are the Lateral and Medial divisions (see Heimer L, de Olmos J, Alheid GF, et al. 1999 The human basal forebrain, Part 1. Handb Chem Neuroanatomy 15:57-226; Sakamoto N, Pearson J, Shinoda K, Alheid GF 1999 The human basal forebrain, Part 1. Handb Chem Neuroanat 15:1-55).

New term, described by Horn, AKE, Büttner-Ennever, JA (1998 Premotor neurons for vertical eye-movements in the rostral mesencephalon of monkey and man: The histological identification by parvalbumin immunostaining. J Comp Neurol 392:413-427) as a premotor nucleus for vertical eye movements.

See note # 8641

The Nucleus preopticus ventrolateralis is a recently discovered Preoptic nucleus, a sleep-promoting nucleus (Saper CB, Chou TC, Scammell TE 2001 The sleep switch: Hypothalamic control of sleep and wakefulness. Trends Neurosci 24:726-731).

The Nucleus ventromedialis posterior (Ventromedial posterior nucleus; VMpo) is a newly discovered nucleus involved in pain perception as part of the Ventromedial nucleus (Blomqvist A, Zhang ET, Craig AD 2000 Cytoarchitectonic and immunohistochemical characterization of a specific pain and tempearature relay, the posterior portion of the ventral medial nucleus, in the human thalamus. Brain 123:601-619).

Replaced from Mesencephalon; for the subdivision of this nucleus, Principal and Magnocellular parts are adopted, following Olszewski and Baxter3. The Ventral division is renamed as Nucleus ellipticus (coming from Cetacea and Proboscidea) or Nucleus of Darkschewitsch, not part of the Nucleus of the posterior commissure.
