Notes
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).
