Taxonomic definition
Taxonomic definition An uncus is a ERR1 of thoracoacromial artery [ERR1 arteriae thoracoacromialis] which lies in anteromedial position relative to the parahippocampal gyrus [gyrus parahippocampalis ], involved in olfactory functions.
Notes
The Uncus is treated in various ways: 1) as the rostral part of the Parahippocampal gyrus; 2) as a structure on its own. TNA suggests the latter. Insausti R and Amaral DG (2012 Hippocampal formation. In: Mai JK, Paxinos G, eds: The Human Nervous System, 3rd ed. Elsevier, Amsterdam, pp 896-942) advocated to restrict the term Uncus to the Gyrus uncinatus, the Band or limbus of Giacomini and the Gyrus intralimbicus (or Uncal apex). The Sulcus semianularis (Semi-anular sulcus) separates the Ambient and Semilunar sulci (see Duvernoy HM 1992, 1998 The Human Hippocampus, 2nd ed. Springer, Berlin-Heidelberg-New York). The Gyrus uncinatus is the most rostral part of Uncal bulge, according to Insausti and Amaral (2012) and part of field CA1. The Limbus fasciae dentatae (Band of dentate gyrus) is the Middle part of the Uncus, first described by Giacomini CH (1884 Fascia dentata du grand hippocampe dans le cerveau de l'homme. Arch Ital Biol 5:1-16, 205-209, 396-417) and part of the Dentate gyrus. The Gyrus intralimbicus (Intralimbic gyrus or Uncal apex) is the most caudal part of the Uncal bulge and part of field CA3.
